Heathkit H11

The Heathkit H11 Computer was an early kit-format personal computer introduced in 1978. It was essentially a Digital Equipment PDP-11 in a small-form-factor case, designed by Heathkit. The H11 was one of the first 16-bit personal computers, at a list price of US$1,295, but was too expensive for most Heathkit customers and was discontinued in 1982.
