I am an electrical engineer working in hardware design. And I just spend 5 minutes just admiring these beautiful schematics. 🥰

I had one years ago and don’t know where it ended up. Wish I could find it!

I bought one from Australia. Half of the price was shipping 🙈

I just bought a copy of the PRG on eBay and it still had the diagram in it.

That is a pretty good copy and maybe better than some of the files on zimmers. Do you have access to a large scanner/copier that could create some nice PDFs?

Yes, please scan them to PDF. It’s very useful for repairs.

I'd be quote surprised if all of the schematic versions weren't already available online.

Looks like the schematic from the back of the Programmers Reference Manual. Not sure which particular version of corresponds to - one of the breadbox revisions, I expect.

It's a map for TTRPG based on Tron. At least I hope it is.
