Comments: This a remarkably flexible machine - sort of a blend between a computer and a calculator (notice the almost seperate calculator keyboard). With 4 expansion slots, an HP-IL interface slot, and a magnetic card reader option, it could do everything from display output on a monitor to controling instruments. It was made from 1984 to 1989 and had a retail price of $595.
