Zenith Z-89

The Z-89 is a personal computer introduced in 1979 by Heathkit, but produced primarily by Zenith Data Systems (ZDS) in the early 1980s. It combined an updated version of the Heathkit H8 microcomputer and H19 terminal in a new case that has room for a built-in floppy disk on the right side of the display. Based on the Zilog Z80microprocessor, it is capable of running CP/M as well as Heathkit's own HDOS.
