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.

Are you looking for a translation? I speak dutch - and there's a number of dutch speakers here on the forum.

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

I believe there is a generic mass storage driver for win98.

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.

By USB 2 I meant USB 2.0.

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.
