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?

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 :)

Looks to me like Nominal Animal pretty much handed him his arse... I feel no need to waste any more time in that guy's delusion.

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

--- Quote from: McBryce on June 28, 2022, 07:41:36 am ---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.

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.

Yep, they are not answering to my email anymore hehe. I might have another solution though. I filled their form and pretty sure it's going to pass now :)
