 ==== Introduction ==== ==== Introduction ====
- +Heathkit released all sorts of electronic kits including early microcomputers, the H8, H89 and H11. The H8 and H89 were Z-80 based systems which supported Heathkit's own operating system HDOS as well as CP/M. The H11 was a DEC LSI-11 based system. In 1979 Zenith bought Heath and renamed the computer division Zenith Data Systems and released the Z-89 as a preassembled H89. Eventually Heathkit/Zenith released the dual Intel 8085/8088 based Z-100 which ran both CP/M and their OEM version of MS-DOS known as Z-DOS.
