The main difference between the H8 and S-100 machines was the bus; the H8 used a 50-pin bus design that was smaller, more robust and better engineered electrically. The machine also included a bootstrap ROM that made it easier to start up, including code for running basic input/output and allowing input through a front-mounted hexadecimal keypad instead of the switches used on machines like the Altair 8800. The H8 was a successful design but required a separate terminal. A successor model, the Heathkit H89 was developed which combined a Z-80 processor board with the Heathkit H19 terminal and a floppy disk drive into one case. This model also was sold in fully-assembled form as the WH89. These were later sold by Zenith Electronics with their name on the front...
