EEVblog #655 - Auction Score
« on: August 22, 2014, 12:00:31 am »
Lots of test equipment auction goodness from Precision Mechatronics who went into liquidation.
And is it possible to mod a system PSU with binding posts?

You will always be able to beat a dealer at auction. They are never going to bid into their profit margins.  They are certain to have a clear limit and will never exceed it.

But they also have commercial clients who will pay top dollar for stuff, so they can often afford to pay more than you think.

The yellow banana will have trouble fitting into the cutout on the system supplies !! :D.
Seriously some nice gear but seeing the inside of the system supply was the real highlight of the video, what a thing of beauty.
I now want one, damn you  :). Guess I will wait for your auction of the excess stuff, (dont you still have gear from the previous 'auction score' ?).
The odd multimeter or 2 or 3 or 4...or........can't remember !.

I have an HP 6622A System DC Power Supply (Dual Channel, 20V@4A or 50V@2A).  It has the same type of terminal strip on the back as your 6641A and 6643A units.  When I got it, one of the channels was dead because the terminal strip had broken the solder joints.  I was surprised to see such a poor quality terminal strip on a piece of HP equipment.  What were they thinking when they specified terminal strips that aren't bolted to the board?

Could these jumper links be the only difference between the 6641-6645 models?, and the different features are just software limited?

We demand 2400 teardown  :P
Would be interesting to compare if it's same to mine.

Your's probably newer, as it have BLUE LED on ON/OFF button  :-DD

Also if you still have those Agilent SMU's, would be cool to put a comparsion :)

Looks to me as if these jumpers are only for identification of the model. They are R901 to R905, located on the buttom right side of the circuit diagram on page 165 of the Service Manual (Figure 6-5). According to the diagram they are only connected one-sided to +5V.

As you can see in the Parts List, there are several differences between the different models (components with different values, other transformers etc...)

why do you need so many repeat units?

Ive been trying to slowly refit my workshop with better equipment, When this auction came along my heart was set on it.
I ended up not being able to bid on anything due to some weird techinical issue with online bidding. frustrating.

Can you give us a rough idea of how much you paid for this stuff at auction?   I've never come across equipment auctions like this in the US .. .I'm sure they are there, but finding out about them is the tricky part.

Yes. I haven't looked in detail yet, but I suspect it sets the voltage and current limits (and associated encoder resolution) in firmware. So you might be able to eek out some extra performance, but surely the transformer has to differ in each model.

Or any other bit of testgear for that matter....

Yes but something that old would surely benefit from a thorough clean-out... Maybe even replacing the HDD with a SSD

There were some crappy ones for 1,000 to 2,000 dollars (US) but the going price for gear you can use seems to be 3000-4000 USD.  I'd guess they would do the equivalent of that well or better in Australia.

Hi Dave,

the  Infiniium Oscilloscope must be one of the first series. You can still see the start button of Win 98.
In later Versions it was hidden. So you will be able to play Minesweeper on your scope  ;) (I did it.)

Will there be any complications in putting an SSD into such an old machine?  I'm thinking mainly of BIOS limitations that might prevent the thing from booting.

Possibly - may need to find an old one, but Compact flash is the same as IDE and you can definitely get IDE to CF adapters.

Just explain the exact process that all of the components use, and the boot procedure of the Windows box. Make sure you copy the data by hand for the extra boring factor. Btw, you made a typo!

Possibly - may need to find an old one, but Compact flash is the same as IDE and you can definitely get IDE to CF adapters.

CF cards are terrible general hdd replacements, they dont have wear levelling and have abysmal random access / IOPS performance
they are ok'ish for bootstrapping custom linux, but you need to take special care not to write too much, and generally keep all the stuff in ramdisk.

cheapest/easiest solution (got one in my laptop) is :
http://www.ebay.com/itm/mSATA-SSD-to-44-Pin-IDE-Converter-Adapter-as-2-5-Inch-IDE-HDD-5-Volt-For-Laptop-/191196101500
http://www.ebay.com/itm/mSATA-mini-PCI-E-SATA-SSD-to-2-5-IDE-44pin-Notebook-Laptop-hard-disk-case-White-/380893918084
+ small mSATA SSD drive ( I got $25 32GB ADATA Sandforce one).

performance with that converter in older laptop:
Code: [Select]
           Sequential Read :    78.959 MB/s
          Sequential Write :    47.939 MB/s
         Random Read 512KB :    78.622 MB/s
        Random Write 512KB :    48.092 MB/s
    Random Read 4KB (QD=1) :    19.962 MB/s [  4873.5 IOPS]
   Random Write 4KB (QD=1) :    33.953 MB/s [  8289.2 IOPS]
   Random Read 4KB (QD=32) :    22.456 MB/s [  5482.5 IOPS]
  Random Write 4KB (QD=32) :    42.393 MB/s [ 10349.9 IOPS]

Maybe you can also replace the floppy drive by one of these (or similar):

its not a floppy, but a LS120 drive (120MB custom medium). Its not using floppy connector, but IDE one (slave to the main hdd)
http://en.wikipedia.org/wiki/SuperDisk

If anything, it would be worth adding USB 2.0 PCI controller card (motherboard of that era has USB 1.1) and put USB connector in place/next to LS120.

Upgrading CPU and ram should also be easy and cheap and should bump performance (at least booting, maybe math).

Cant wait for scope teardown. Wonder how its build inside. Is data touching cpu at any point (FFTs?) Is it a PCI card or all one one custom motherboard? is it all in asic? What does the display, also asic or normal GPU of the day?

Thanks for the clarification.  :)
I thought it was a floppy drive.

From the datasheet:
Quote

120 MByte LS-120 SuperDisk floppy drive to store waveform data, screen images, or scope setups...

I would imagine that most flash memory applications are using the same memory controller ICs, so it make sense for nearly every flash memory device to support wear levelling by now.

PCs of that vintage tend to have limits on the hard drive size for various historical reasons. 8GB or 32GB are the ones you run into most often, and the 32GB limit is very common on late 90s Award BIOSes (as the scope seems to have if I'm squinting at the screen correctly).

Simple reason the bus mouse did not work is that it has to be plugged in at startup so that the windows kernel driver is loaded, as otherwise windows does not ever look again for one, and assumes a serial port mouse is there, or for later versions a USB one. That one still has a ball inside, I still have some PS2 mice around, and even one serial mouse.

In a scope I can't see that it would be writing to the disk very often, so probably not a big deal

You just need enough memory and then you can run Win98 without a swap file. It will complain when you set it up, but so long as you have enough RAM and limit the applications that are open at any time ( and have no major memory leaks, but then again this is Win98 which falls over for this in any case after a few months) you can do it.

On my Infiniium Oscilloscope (54810A saved from a trip to the dumpster) i have put a bracket on the back for the build in USB ports and upgraded the RAM, CPU and even added an audio card because those scoops have a free software upgrade for voice recognition :P

Those scoops have a separate PCI acquisition card that write strait to the video frame buffer and use a little RAM disk to store your settings so the harddisk is only used during startup.

Also free_electron has posted some images of those scoops on the dutch forum circuitsonline

Concerning the infiniium scope, you may try the following:
Open up the start menu by pressing ctrl-esc, launch paint and start drawing with the colour 10, 9, 9 (r,g,b) selectable in the custom color dialogue. You'll see the hardware replacing that color by the actual waveform display. That's probably why these scopes were so responsive, even back then

At 20:05  Dave is showing the front cover and it says Infinium on it instead of Infiniium
Did the early HP versions got spelled with one  "i" instead of the double "ii"?

Yes. My HP Infinium is spelled with one "i" on both the cover and the scope itself.

why do you need so many repeat units?

It was 5 PSU's in one lot.

It just doesn't look good Dave. I'm sure there were a lot of young players who would have loved not to have been out bid by a guy who gets his equipment for free.

You are right. Youngsters don't need quality equipment. But then they also don't need the good advice you have provided in your videos either in that case.

It's your lab dude, you can hoard all you want. I just think its incongruous with your current philanthropic image portrayed by your educational videos and some (not necessarily me) may see it as a suspicious contradiction.

Don't put words into my mouth.

Fact is youngsters are almost certainly not going to bid on a bulk lot of 5 system PSU's.
By your reckoning I should never ever be allowed to bid any any piece of 2nd hand test equipment ever again (be it ebay or whatever), lest I rob some youngster of an opportunity  ::)
That is one of the most ridiculous things I've ever heard.

You can think anything you want, but I certainly don't agree, and quite frankly you are in no position to tell me what I should and should not buy with my money.
By me buying and selling 2nd hand gear (as I've always done for a hobby, and now you are telling me I can no longer do as a hobby)
a) Gives me material for the blog. i.e those youngsters get to see inside gear they likely may never be able to afford (hint, this stuff was not cheap)
b) Gives me some extra income that keeps me in business
c) Occasionally gives me some cheap-ish stuff to give away to said youngsters

Your inability to answer the question is duly noted.
I'm not putting words into your mouth. You have made it very clear that I should not be buying any 2nd hand gear.
I can see why you think that, but I think you are demonstrably wrong, and have explained why I continue to do so.

Facts are this:
1) My buying some 2nd hand gear is borderline insignificant in the scheme of the number of people who are doing this. You'd be very hard pressed to prove that I deprived a youngster of some gear.

2) My providing videos about this gear unquestionably and demonstrably helps youngsters.

3) Buying and selling this gear provides some income to help me stay in business so I can provide that free content to youngsters.

4) My buying this gear provides me a cheap-ish way to give back free equipment to youngsters which I occasionally do. The other month I gave away two scopes for free to youngsters. That was under the radar, no publicity at all, but now you are forcing me to defend myself so I'll bring it up.


So how exactly does your argument stand up against those facts?

[/quote]

There some serious misunderstanding going both ways I think.

1. the Donations thing was not to you but to the other fella who claimed you only buy/sell for a living. I was showing that not to be the case thats all.
2. Donations perfectly legitimate. I have donated and still continue to donate  - mostly because I appreciate the education I get.
3. Buying / selling gear is perfectly legitimate for anyone including yourself.
4. Buying and selling gear for a living while accepting donations for your educational video's MAY (does to me) look suspicious IF you are buying 5 power supplies. Because at those quantities it looks like donations are supporting your buying/selling business rather than the actual educational videos.
5. To make it as clear as filthy mud, I am absolutely NOT saying you should stop buying/selling, buy/sell less stuff, buy/sell other stuff, leave the planet, grow a beard or get a sex change.
6. I AM suggesting to you - as what was meant to be a simple suggestion without malice or offense- that if you buy large quantities of the same item at auction you may want to at least not tell the world about it if you want to keep donations coming in and Yes I know many of you wont understand why but trust me the youngsters will. - this is especially true if you get a lot of your equipment for free these days.

I dont know why this is so hard to understand or where the confussion is coming from.

How is that better exactly?

I understand, but I think you are wrong.
And I don't have to take your word for it, because youngsters tell me every day what they don't and don't like.
You are the very first ever in 5 years of me doing this to say it looks bad me buying 2nd hand gear.
The numbers who have complemented me on my auction and other 2nd hand gears videos would be in the hundreds, maybe the thousands.

no one will tell you they think you are disingenuous, you wont hear from them at all.

When I donate I am usually careful. I dont like being taken for a ride. If I suspect a person or organization is using my donation to support their hobby or to start some crazy business I go nuts. Im sure others are the same - at least those who frequently donate.

as for the above about me saying shouldn't buy stuff to tear down, obviously you haven't understood me at all.

to come at this from another angle.
1. Keep the tear downs coming because I find them usefull comparisons when I design my own things.
2. Do whatever you have to do to support yourself and your family (legal and ethical ofcourse)
3. I suggest you may be missing out on a world of donations that you arent at all aware of.

You were right to bid. I would be disappoint if you didn't.  However maybe not right to brag about it. That didn't look good

Dude, really? "It's okay to do it, you just can't be happy about it."

How does it hurt anyone if he buys stuff, talks about it, brags about it, whatever? That's why things are sold - so they can be bought.

nutso.

that's not nice.

You're right, I'm sorry.

You were right to bid. I would be disappoint if you didn't.  However maybe not right to brag about it. That didn't look good

Right. So you've gone from saying it's depriving some youngster of gear, to it now being ok. Thanks for clearing that up.

This is how i picture you dave while reading this thread lol  :P

on a side note it was actually one of the early auction score videos that made me feel like some of this test equipment is obtainable, Compared to the prices seen on ebay. So keep up the good work and it would be interesting to see what this stuff is worth locally in Australia? I suspect its a fair bit less then in America.

Good on you Dave, hope you got the unit for a reasonable price and make a lot of money selling them on ebay.
We get the benefit of getting to know different types of gear and what they can do.

As for the youngster, who has no clue about auctions and doesn't understand lot pricing I would say, grow up! you are the only one who has a problem with this.
And yes people would say something.

I think and believe most of majority of Dave donators are thinking ... "Good to see he is biting again, so their penny worth of donation will help him to bite "MORE" in the future and hopefully supports him in getting MORE video's materials"  >:D

Hey Dave, check these terminals out and see if they are the correct size for your Agilent PSUs' boards. Since Agilent used AMP (Tyco Electronics) fully insulated faston terminals on the wiring for the transformer taps and such, I'd be surprised if they hadn't also used PCB mounted terminals from AMP to bring out +/-/gnd from the board to the front panel too. (Likely the .250 [6.35mm] series)

http://www.te.com/commerce/DocumentDelivery/DDEController?Action=showdoc&DocId=Catalog+Section%7F82004_FASTON_PCB_Tabs_Receptacles%7F0311%7Fpdf%7FEnglish%7FENG_CS_82004_FASTON_PCB_Tabs_Receptacles_0311.pdf

http://www.te.com/commerce/DocumentDelivery/DDEController?Action=srchrtrv&DocNm=82004_FASTON_TERMINALS_-_FULL_CATALOG&DocType=CS&DocLang=EN

It also kinda looks like the front panel cutout might have been designed for up to 6 binding posts (possibly for some optional sense terminals?)

Does the schematic show if those output capacitors are X/Y safety rated? From the board layout, they look like they are film types, and since they connect to the chassis ground, they could possibly be safety rated types. [...and in looking at the video again, I see the same capacitors at the rear jacks are marked "10n Y2", so they are indeed Y2 safety rated] They are probably only there for EMI/RFI purposes though (I remember getting a lecture about a device without these being considered an "intentional radiator"), so if you were going to just keep these PSUs around for the lab, you could probably just omit them... ;)

In looking at the video again, those large white locking wire to board connectors are also AMP/Tyco (specifically their Universal Mate-n-lok in polyamide, which is why they are white instead of semi-translucent nylon) so I guess Agilent used AMP terminals and connectors extensively.

mmm cable porn ;)

The opposite in fact.
2nd hand test gear is much more expensive here than in the US because of limited availability.
It's very easy to buy gear from the US, pay a huge amount of postage and still re-sell it locally for a good profit.

Think Au is bad try ZA. Here it actually is cheaper to buy from Australia and ship here than pay local prices. I have done that. I also find a lot of eBay sellers will not deliver to here either, so have it shipped half way around the planet then shipped back. Amazing that it takes 4-12 weeks for stuff to get here from China, while for the same stuff to get delivered to the USA is around 4 business days.

China (and Hong Kong) used to be amazingly quick to Oz, as little as two days. More than a week and you knew something was wrong.
That was before all the new US imposed postage regulations et.al
Now it's several weeks minimum.

4. Buying and selling gear for a living while accepting donations for your educational video's MAY (does to me) look suspicious IF you are buying 5 power supplies. Because at those quantities it looks like donations are supporting your buying/selling business rather than the actual educational videos.

I don't think you understand how proper equipment auctions work. The 5 PSUs were one lot. They are not interested in selling single items unless they are high value.  They are not interested in even the chance of missers bidding. A live auction will want substantial deposits paid before you can even bid.Items must be paid for by cash or bank transfer on the day. Plus tax and auctioneers fees are added to the hammer price. All in all they are not for the faint hatred. Oh and if the items don't work, that's the buyers problem.
What Dave will do by testing/calabrating/fixing and then eBaying them one at a time, adds back to the community.

Core is Dave is risking HIS OWN MONEY on this. Auctions are Voetstots, meaning there is no warranty on the stuff, either implied or actual, and no return on them for any reason, as you are deemed to have bought after inspection and accept any defects or non working as part of the deal.

auctioneers do not have either the time, skill or any reason to actually test the stuff they sell. they are in the job of determining a "Fair market price" of the goods on each lot, and the work involved on each lot is pretty much the same irrespective of the actual amount of stuff on the sheet. If they see there is a lot of small lots from a same seller they often will consolidate them into larger bundles, as this both lessens the amount of time spent doing the suction and decreases the commissions paid by the seller. These typically are a per lot cost, with a variable commission on the sale price as well. Thus they will not sell as each, but will bundle till it fills a pallet typically for movable stuff. You might find a pallet of multimeters of assorted types, and this might have a large variety of different levels, but will go as a lot.

Typically if you ask an auctioneer to split out a part from a lot you will pay a lot higher price, often more than the rest of the lot as a whole. When I go to auctions and buy lots, I take the whole lot, and if I was only interested in a single item or two I often will place the rest on the next scheduled auction and get a part of the money back as well.

Dave

Please carry on buying test gear, either on Ebay or at auctions. Why?

1) I am quite sure that test gear which is surplus to requirements ends up sold by you on Ebay, AFTER being checked out and tested. This ensures that the purchaser gets a good item. A good example are the ex-Australian Air Force scopes.

2) We get to see test gear 'in the flesh' that we wouldn't normally see.

3) Teardowns  :)

4) It finances the blog, all those cameras are not cheap.

5) It means that you can split one big lot (such as the power supplies or scopes) into individual items and therefore makes it more affordable for those 'young players'.

6) Because you can! If anyone else wants to travel to the same auction as you and bid on the same items then they're welcome to do so, that's the way the system works and if you don't take part then you don't get the goodies.
Should you find yourself in a chronically leaking boat, energy devoted to changing vessels is likely to be more productive than energy devoted to patching leaks.

When I go to auctions and buy lots, I take the whole lot, and if I was only interested in a single item or two I often will place the rest on the next scheduled auction and get a part of the money back as well.

At live auctions, which seem to be less common these days,  if there were several similar lots coming up you could easily ask the auctioneer to give the high bidder the right to choose all or some of the following lots at the first winning bid price. It saved the auctioneer time so they often would do that.
In the past I found it to be the opposite - where there were many similar lots the auctioneer would by default offer an option either to take any number of lots at the winning price, or sometimes to pick & choose, but they would sometimes  accept an objection from the audience and offer seperately if there were significant differences.

You were right to bid. I would be disappoint if you didn't.  However maybe not right to brag about it. That didn't look good

Part of Dave's job is to "entertain" people.
And why not brag about a great auction score.
It is also a kind of entertainment and it is OK.

Why are so many people watching Dave's videos on his blog?
Definitely not only because of the technical information.
But the kind of funny entertainment he provides.

Look at some technical videos of like a Tektronix or Agilent YouTube Channel.
They are lucky, if they get a few hundred view in a year.
Because they are not entertaining.
There are 3 kinds of people in this world, those who can count and those who can not.

No, more like real life. Dave asks for donations if you want to give, and around 5% will donate some small amount. Either I give to Dave, and he does as he wishes as it is now his money, or I give to Martin, and the same. Giving to others that cam use it in some way is good, and that as a bonus you actually get to see what part of that becomes is a lot better then giving to charities that are opaque blobs.

The following just showed up in my feed.........

If you really are thinking that Dave is going to get rich from charities and ebay sales you are more delusional that you come across now.
If you are self-employed and have family to take care of you really need multiple income sources, just like most musicians have 3-4 jobs (orchestra, teaching, small band).
I think you are just upset you couldn't bid on these items, like you mentioned in your first post.
Dave is running a business and putting money into expensive equipment is actually a business risks, this stuff could be broken and or take a long time to sell,
all the while his money is tied up and can't feed his family.  From your posts all things you seem to have no clue about.

I think you are really the only one who is upset about this and expect jealousy.  If anyone else is upset they would have come forward right now (if they are people please come forward ...).

Yes, as I've explained before.

Yes, I think it's a real win-win, and is why I get stuff from auctions.
a) It gives me content that people enjoy (even Cside admits he likes it and wants me to do it)
b) I actually enjoy doing it
c) It is potentially another income source, or source of cheap gear to giveaway. But often I'm just happy to break even on auction stuff I buy when I get a video out of it. Sometimes I might even make a loss on something, and justify it that it was money well spent on the content.

Given that Cside's real problem now seems to be that I "bragged" about it, well this was hardly bragging, as as I've said I paid a lot of money for this stuff. If there was any bragging it would have to do with the fact that I got anything at all at this auction which was incredibly fierce. I"m taking a big risk here that I can actually resell this stuff for some profit after I'm done making content with it. Perhaps enough profit to pay for keeping a couple of the items for the lab.

He is doing it to supplement his income because that's part of what he does for a living.
He has the expertise to test such equipment and sell it, not everyone that flips liquidation equipment to ebay has that expertise.

As for the ass kissing comments, that's not nice, so don't expect members to be nice to you.
There is nothing wrong to earn a living doing the blog, auctions, donations etc.

And I don't recall Dave getting a lot of free test gear, he has gotten some and some of them were on loan for doing a review and then returned back.

What you don't seem to get is that he is not spending the money, he is using it as an investment to make a profit after inspecting and repairing if needed to supplement his income, because we all deserve to be paid for our services regardless of receiving donations.

c) It is potentially another income source, or source of cheap gear to giveaway. But often I'm just happy to break even on auction stuff I buy when I get a video out of it. Sometimes I might even make a loss on something, and justify it that it was money well spent on the content.

Given that Cside's real problem now seems to be that I "bragged" about it, well this was hardly bragging, as as I've said I paid a lot of money for this stuff. If there was any bragging it would have to do with the fact that I got anything at all at this auction which was incredibly fierce. I"m taking a big risk here that I can actually resell this stuff for some profit after I'm done making content with it. Perhaps enough profit to pay for keeping a couple of the items for the lab.

Dave that is not fair.

Anyway you know exactly I am driving at, you may not publicly admit it.

It looks really bad for anyone who asks for donations to be buying up excess equipment you just cant reason your way around that.

and seriously some terrible ass kissing going on in this thread.

No, more like real life. Dave asks for donations if you want to give, and around 5% will donate some small amount. Either I give to Dave, and he does as he wishes as it is now his money, or I give to Martin, and the same. Giving to others that cam use it in some way is good, and that as a bonus you actually get to see what part of that becomes is a lot better then giving to charities that are opaque blobs.

The following just showed up in my feed.........



think about it.

Oh my god that video. No sources? Where are the papers? I want to see the studies or write it off as the quality propaganda that Goebbels would be proud of. What is the motivation for this video? who made it and what do they have to gain by it?

Nice one, Wilfred!

You know, I'd probably not pay for a professional calibration of anything that I own since I'm not at anywhere near that level of need, but it would be nice to pick something up from a reputable guy like Dave who can at least give you a certain level of calibration confidence against something he owns and uses.

I have a question.  I have a 1GHz Infiniium scope and in the video Dave mentioned replacing the floppy drive with a USB device. I have searched in the past for these type things and found them to be expensive. Switching Power mentioed a Dutch website that shows some things but my Dutch is rusty.  Does anyone have some light they can shed on this for me?

BTW, I whole heartedly support Dave financing the blog with auction finds.

Those are not floppy drives but LS120 drives. They sit om the IDE bus.
An ls120 disk can hold 120 megabyte and read a standard floppy as well

Yes a translation would be nice.  I didn't see any language settings at the top of the forum.

If I can buy a PCI USB 2.0 card and stick that it in that would be great.  I'd like to know more about RAM, etc too.

My Infiniium is in dire need of a new BIOS battery.  A guy that I work with told me to write down all memory settings, etc before I replace it.  Does anyone have any info about this process by chance?

I don't know if windows 98 ever supported USB 2. I do know XP requires a patch for USB 2 though.

Does the scope have a standard motherboard inside?  I'd love to see how far the PC side of the scope could be upgraded.

It does and worked reasonably well. The original Windows 95 release did not support USB. Windows 95 gained USB support with the OSR2 release.

The board in the scope looks like a AT form factor Socket 7. The last AT form factor boards that I can remember were Pentium II, which isn't worth upgrading to (those massive cartridge form factor CPUs). Another upgrade option which is quite likely to work if the board has the correct voltage ranges is an upgrade to an Intel Pentium 233 MMX or AMD K6-II or K6-III. Some of the K6 processors ran quite hot though, so cooling could be an issue. One more option would be an industrial passive backplane and a single board computer. Those are available in all sorts of processor types, but supplying the correct power for a more modern SBC could be an issue if the scope's PSU is set up for powering an AT form factor board (no 3.3V support).

98 supports USB but needs a driver for USB memory sticks - I think it needed a specific driver for each make of USB stick.
Although Win95OSR2 supposedly supported USB, IME a lot of USB drivers didn't support 95 so it wasn't much use

There is support for USB memory in Win98SE, but it can be very spotty as to what drives work, and often it needed a driver which then got a lot of other drives working. It also had some issues with larger drives, typically it would not work with drives over 4G or with some anything over 1G would work spottily. most of the time it would only work at USB1.1 speeds, even on a USB2.0 drive connected to a USB2.0 chipset. 12Mb per second transfer rate instead of 100Mb per second that later drives could handle.

Also before going down the PCI - USB route make sure the scope software isn't hard coded to expect an A: or B: drive letter.  IIRC USB was only introduced later in the lifetime of Windows 98 as Win98 SE. So that may be an additional hurdle.
The older scope software is hard coded to only accept scope software updates from a 120MB floppy as drive letter A: (with "subst" in dos you can mount any folder as A:)
For storing screenshots and other info it uses the build in windows explorer so you can safe things anywhere windows can access.

The motherboard in those scoops have build in USB 1.1 support but is disabled by default, to use it al you have to do is buy a 2 port usb bracket and enable usb support in the bios.
If you want faster usb you can buy those usb 2.0 cards and plug it in the spare PCI slot (use something with a NEC USB chipset, mine did not boot with a VIA USB chipset) and install the generic storage driver with usb 2.0 support for windows 98 first edition.

If I can buy a PCI USB 2.0 card and stick that it in that would be great.  I'd like to know more about RAM, etc too.

My Infiniium is in dire need of a new BIOS battery.  A guy that I work with told me to write down all memory settings, etc before I replace it.  Does anyone have any info about this process by chance?
Check what model Infiniium you have and download the Service Guide for it all the info is in there. For mine the RAM are standard 72-pin SIMMs you can get those on eBay.
All the bios settings for Infiniium series 548xxA are in the Service Guide starting at page 106, in some older scops the bios battery is embedded in one of those dallas clock modules.

Anyone trying to upgrade there Infiniium scoop should definitely check the Service Guide because there are many different motherboards used in these scoops all with different bios, memory, usb and floppy/cdrom options so dont go and buy stuff without taking the cover of your scoop to see what's really inside of it.
