I've got an HP-85 that I am offering to the list before I put it out on Ebay, the price is $200.00 plus shipping. The unit is fairly heavy (approximately 75 pounds) as everything is contained in a wooden plywood box. If the box is not wanted, I can repack it separately which will reduce the weight. This includes quite a bit of stuff including approximately 50 tapes including several that are the original HP tapes, manuals, Rom Pak cartridge, six rolls of HP Thermal Printer tape, and a modem with the HP Modem Communications Tape. This worked the last time I checked, and the only problem was the drive roller for the tape drive went soft and needs to be replaced before using. In any case, if it doesn't work (and I'll check it out before shipping), I have several and will make sure the one that ships works :).
