Someone on this list, perhaps you, Doug, expressed an interest in it. I know I have the service docs in a different box, but for now, I've found the board itself. The 40-pin chips have gone wandering (probably in my parts drawers); I'd like to know what sockets are supposed to contain what parts (probably a 6502A and a couple of 6821's) so I can locate them and put them back. I will probably never run across a real Challenger-4 for this to go into, and I have no interest at this point in fabricating the necessary accessories to make this useful. I anyone wants this board, contact me offline. I'm interested in trades over cash - 1970's micros of most kinds are interesting to me. Enjoy, -ethan ===== Infinet has been sold.
