If anyone is interested, I have an HP 85 available. It works intermittently - it's nothing that re-seating the chips in their sockets fixes! The printer works - don't know about the tape drive. I can pack it, but you will need to pay shipping (and promise to send me your next 'extra' Altair <g>). I can also throw in a new roll of thermal paper (besides the remainder of what is in the unit). I'm near Hartford, CT. email me privately with any bribes. Bob Stek Saver of Lost Sols
