When I got these boards - the guts of a decommissioned Twin cabinet, I contacted a few experts to help me with a simple display to showcase the self-playing demo, or whatever. I never thought I will be able to build a working, playable, linked system! Communication boards were a lgift from a friend who sold me the guts in the first place. These were non working at that time, but after exchanging of dead Z80 processor, the two boards started to communicate (through an optical cable! We're talking year 1992!).
Powered through a single 300W PC PSU. Opened to showcase the boards.
Very happy to show you this beauty!
