You wrote: I have two unmodified Honeywell DDP-516 computers available for trade in the Netherlands. Both were still performing their original job (in the USA) back in 2000 and are in excellent condition. For years I've tried to locate other DDP-516 owners, but it seems I'm the only person left on this planet with Honeywell DDP-516s. They are pretty interesting minicomputers with a nice story... Contact me directly if you are interested in working something out. Sincerely, Erik.
