Nobody wants to take a stab at this?
Anyone interested in more of this kind of stuff?
I am, but purely from an aesthetic perspective, those hand drawn tracks are a joy to behold. I could take a stab at it's function based on the component layout and interconnectivity, but I would never for the life of me be able to pick the kit it came from. Maybe we need an "Aesthetic Kit" thread to celebrate the wonderful examples of design and construction I'm sure we all have in our collections? I nearly fell off my perch at the site of that AKAT-1 earlier ITT, what a time capsule of engineering and design that machine is.
Meanwhile, who wants to take a swing at this critter? Came to me in a bulk purchase of ISA cards. It's labelled as a A3103-200901, ROM is labelled SS5206, neither return any hits on or the usual haunts for card info (uncreative labs etc) or on the Google.

It has a UPD8255AC-2 PPI in its guts and some rather clunky voltage regulation circuitry on the right, featuring open base transistors and trimmer controlled voltage dividers which feed a TL487ACN. The thing has a 66 pin header on the back, but I don't know of any drive or peripheral standard that utilises this number of pins. Trace tracking reveals only about 16 of them are in use anyway, the rest are open. No info on the back short of a QC sticker. I suspect it may be an interface card for some sort of external sampling instrument due to the separate and calibrated power supply, but I haven't the faintest.
Thoughts?
Unsure What this is, They were throwing it away at school and I thought it might have been worth saving.
