Picked up a COSMAC hoard

[falter]

Hey! I've not been around much due to work and life. Honestly, I haven't really been buying anything lately either. But this month I hit upon a few things that were long on my list and decided to reward myself a little. I'm wondering if any COSMAC gurus know what some of this stuff I bought is.

I paid $450 for the lot. My primary target here was the COSMAC ACE stuff, which I've never seen come up for sale before. I know Tom Crawford of ACE - he provided me with his homebrew CT1024 and some vintage artwork, some of which relates to the ACE. Being that ACE was a Canadian group to start, this is really special to me and isn't exactly easy to find, so on that alone I think it was worth it. But the other stuff attached is worth some bucks too - I know I've seen one of those Netronics ROM boards go for $$ before.

I recognize probably most of this stuff but there's bits I don't, like what look like huge RAM boards, and a few unbuilt boards. Wondering if anyone here recognizes them.

Hoping to get back on track, pick the thread about learning about power supplies up again and actually start getting some projects moving. With US-Canada tariffs coming I have a bad feeling I'll have lots of time for geeking out soon enough. Maybe too much.

the ram boards really look like someone was bodging something entirely different into a not-S100 bus that was then adapted to the ACE.
I feel like there's an extra board or adapter that's missing.

I got the boards in today - here's some higher res photos.

Trying to figure out if these were mostly part of a system at one time - ie maybe the builder started out with an ELF II, then got involved with the ACE group, then started building/built an ACE out of it. One of the boards is an Exidy Sorcerer power supply board.. not sure how it got in the mix there but there it is.

Man, there is some absolutely WILD bus hacking going on there.

Curious collection. 2114 SRAMs with house numbers; some with ID's completely sanded off. This must have been a collection built by a hobbyist.

I'm thinking whoever it was was definitely into 1802 stuff, and may have hacked those RAM boards from something else to support either this ACE or something else. The video board not being built and the FDC board missing parts kinda makes me think they were working towards an expanded ACE system but maybe didn't get there.
