Heathkit/Zenith Data Systems Computers (1977 - mid-1980s)

Heath Company was one of the key players at the beginning of the personal computer revolution. Today, most people carry vastly more computing power and storage in the form of a small phone. These early systems had processors which ran at 2 MHz, supported at most 64k of memory, and used floppy disks which supported about 100k.

In the mid 80s they started making IBM PC compatible systems, like most of the industry. They had some excellent designs/systems, but this site is focused exclusively on the pre-IBM PC computeres, their software, and accessories.
