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

Initial memory limitations restrict the selection of system software, but the system RAM can be expanded to 32 kWords * 16 bit. Many PDP-11 operating systems and programs run without trouble. The system will also work with most DEC PDP-11 equipment, including many Q-bus compatible peripherals.
