Greetings, I have a friend that is looking for a DN4500 or DN5500. Unfortunately he is in the hospital right now. He had a serious case of spiral meningitis and has been unconscious for a week. The doctors are pulling him through!!! I'd like to keep in touch and maybe he will be interested in a month when he is recovered. He has a DN5500 that was fully intact, including a cartridge drive, but the clock battery leaked acid on the motherboard and it will no longer work. But the disk drive, RAM, cartridge tape, etc. all work. So making a binary image of the tapes seems possible. Both of us used to be Applications Engineers for Mentor Graphics :-) see: www.hunkler.com/aegis.htm Thanks, Tim Hunkler
