What is this?

[VintageComputerman]

This is from a collection of stuff I got last year. I have no idea what it is. There are two power supplies connected. It looks custom built. The person I got this from worked as a project manager at, I think GE. Maybe it's part of an old industrial controller or a phone switching system, I have absolutely no idea. There are a few MOS chips on the one card. Everything is wire wrap too.

Any help in identifying this will be greatly appreciated. I have more photos of related cards too. Besides identifying what it is, I'd also be interested to know what it might be worth.

Well, the fact that it is wire-wrapped and that they seem to have used it for real time data acquisition would suggest that it is either a prototype of something or, more likely, a "no one makes anything to do what we want so we'll cobble something together" one-off to do a specific task.

You'd be surprised. I've worked on several systems from the late seventies to early eighties that had production runs of 50-100 systems, with all of the circuit cards wire wrapped. It was apparently cheaper than doing a short run of pre-built cards.

Unfortunately, this isn't one of the ones I've seen.

But what might it be?

Are there any chips of value in that mess of circuits?

Maybe I should just pull it apart and frame the cards as mementos from the past.

I have several identical power supplies with related parts and hundreds of related IC's, etc, from that area.

I can tell as much as the MOS 6526 is a CIA (complex interface adapter) as found in the Commodore 64, B-series a few others. It suggests these cards were manufactured no earlier than c:a 1982, perhaps 1983.

Hi
All the cards seem to be I/O. I don't see a processor in the lot.
GE made a programmable controller that one put modules onto.
It had a CPU ( Z80 as I recall ). Each module did different things.
These may have been prototypes for these modules.

It started very old and electrical appratus having starange kind of appearance. It has power supplies and circuits and looks amazing.
