Abstract
This paper compares the highly similar PDP-11-compatible microcomputer systems sold by DEC and Heath (also Heathkit). Heath now offers software and factory-assembled hardware at 20%–40% less than DEC’s lowest priced floppy disk microprocessor system. The first author started a reaction time laboratory with factory-assembled components. The second author built a similar system from kits and adapted CAI programs developed on a conventional PDP-11 minicomputer. Both experiences are reported in this paper.
