About the Heath Co. Heathkit H11
In the Q-bus the highest 8KB addresses are reserved for devices. Thus, the system can contain at most 56k of real memory. The processor (lsi-11/2) ran at a 380 nanosecond average cycle time which is approximately 2.6 Mhz. This was relatively fast compared to its parent the PDP-11/20 minicomputer(1970) which because of its magnetic core memory ran at a 800 nanosecond cycle time.
