Description VINTAGE  The H8 was the first 8080 computer made by Heath. It had a sloping front panel mounting a 9-digit keypad which could be used to program it in machine language. However, it used octal notation rather than the Hex notation which was used on the S-100 machines. It was a bus machine with a unique 50-pin bus. Expansion cards and peripherals were available for the machine, including the memory and speech cards, the H7 floppy disk assembly, and the H10 paper tape reader/punch. The H8 needed at least 16K of memory for nominal operation and 48K if a floppy disk was to be used. The maximum memory capacity was 64K. The H8 had no internal video but was designed to be used with a terminal such as the H9 Video Terminal which had a 12" CRT.
