I have an Intel PDS-100 Personal Development System but no manuals or information on this unit. It is from 1979-1982 I believe, and has two prom programming boards with it. The unit is the size of a slightly large pc, has a carrying handle with built in monitor, keyboard and two 5 1/4" half height floppy drives. Any information would be greatly appreciated.
