There was a lovely more or less complete final prototype on ebay a week or so ago. It was from Ed's collection, he made it along with Marcel. We have the schematic and a couple of bareboards. Josh B. is going to re-work it (like he did with Ed's ELF II and Hyperboard) and make the gerbers available. We dont have gerbers for the board that was sold on ebay, but basic aspects of it were tested, and Ed has some pictures of it playing games from the boards roms. It was fun playing with it.
@waltermixxx sounds like a plan and a nice way for the work to live on. The COMX/COMiX 35 could definitely benefit from more homebrew hardware addons out in the wild.
