I don't think 2.4 micrometres of armour is going to make much difference.  >:D
Sigh. The other nm in common use all around the world, i.e. not just USA.

So I printed the PH-163 casing. Fit's perfectly and seems relatively safe to use, but the creator neglected to mention which terminals he used. Has anyone an idea what terminals would fit the PH-163 pins? Or what terminals these are in his picture? https://3dmixers.com/m/268285-ph-163-connector-hp-oval-

Did you print it in PLA? It's hygroscopic. I wouldn't put mains near it.

My approach on these in the future are going to be making a blanking plate with a cable strain relief and either a dangling IEC socket or a captive mains lead.

Although I managed to avoid that at the weekend with the 400E as it had an IEC already

Yeah, I know, but I've read up on it and it's all a bit scare-mongering exaggerated. It never absorbs enough water to become dangerously conductive. There are documented experiments where a PLA part was left underwater for several years and it still kept its structure and isolation.

A IEC 60320 C6 "mickey mouse" inlet can normally be fitted in place of the old HP inlet. Often without changing the original metal work

I was hoping to keep it as original as possible, but I will keep that in mind for "Plan B".

If anyone wants this go go go go. 500Mhz scope plus Agilent PSU £180. I can’t take it due to delivery constraints.

Wow thanks for that ! I never knew this series of scopes, HP branded / nice looking, were available with such high specs and a COLOUR screen ! :scared:

I learned something.....  :-+

High bandwidth, colour screen but not a megazoom so only 5k pts memory depth.

Could easily double that money just by putting it back in a box again  :-DD. I would but I'm too busy  :-\

Yep no Megazoom if just I guess because with 2GS/s sampling, 10 times more than a Megazoom, it would have required too much memory for the day, and more importantly I guess so much ASIC performance that it would have been either cost prohibitive even for high end HP stuff customers, if even at all technically achievable at the time.

That's where I will concede the modern scopes a clear advantage. Technology/performance has improved to the point where you can have both high BW / sampling rate, and deep memory at the same time, and you can set the trade-off between the two on the fly as you require, to suit the job at hand as best as possible. High time resolution versus high refresh rate to find rare events.

That's the main selling point to me, if I were to ever be in a position to be able to spend money on a modern scope.
That, then next selling point to me is the large wide aspect ratio screens that give you a lot more real estate to see your signals.

Postman has just dropped off the Commodore F4902 calculator, but sadly the last digits of the 11 digit plus +/- display have segment "A" missing, which is not quite the end of the world but still annoying as when the digit displays 1 there is no real way to work out if the 1 is correct or should it be a 7 :palm:

This is a one chip calculator, keyboard matrix and the bubble LED digit display, there are no other parts to it. All connections have been checked and test out OK, no bad connections or broken tracks, so it has to be either the display or the chip.

I'm leaning towards the display itself, does anyone know where such displays may be obtained from these days?

Yes, old calculators is a source, problem is that these don't often come up for sale very often these days. I suspect most of these LED type calculators just get dumped nowadays as people don't believe there is any value left in them. I actually prefer the look of a nice red LED, green LED or the green florescent displays, so more relaxing on the eyes and warm feeling.

Or old people who have spare components. I have a box of similar displays (some even from Commodore calculators). Can you post a picture of the display component and I'll check if I have one.

Cheap Teledyne (rebranded Siglent) scope on ebay this morning. Brand new, 275$. 2 ports 100MHz 2Gs/s 140MPts. Can be upgraded to 300MHz  :)

   https://www.ebay.com/itm/165537662690



Ehhhhhhh.... might be worth taking a punt at that price. Weird feedback, tho there do seem to be plenty who actually get their stuff as well. :-//

 :-/O

Yeah peoples were talking about them somewhere on the forum. Look like they are a bit like Keysight where they just want to sell to business and not individuals. From what I can read in there listing, should be fine buying from the states.

I'll let you know just ordered one of those  ;)

Edit: the discussion was not over here but on groups.io https://groups.io/g/LeCroyOwnersGroup/topic/lecroy_ebay_store/989710?p=,,,20,0,0,0::recentpostdate/sticky,,,20,2,0,989710,previd%3D1655564782545298826,nextid%3D1651335155808914573&previd=1655564782545298826&nextid=1651335155808914573

Update: Item still not shipped, they only want to sell to a business. Trying to make my way through this burocratic maze  :scared:

Hmmm, your search might be more difficult than I thought. I found 3 Commodore Calculator displays and all of them are different. The older CBM Calcs are VFD, the newer are LED but the one's I have are 9 or 10 digit devices. Yours has 11 digits.

Two examples below. Note the cute little DC/DC converter daughter board for the VFD :)

I've considered that scenario myself... and while I'd probably think twice aboot it with 240V mains like youzz guyzz have, at least over here with our "kiddie-pool" 120V mains, I'd probably just cover all the contacts with heat-shrink tubing and call it good.
