Monads II was a hardware prototype of the architecture which characterized all later Monads systems. It was a Hewlett Packard 2100A minicomputer that was modified by David Abramson to incorporate address translation hardware for large virtual addresses and protection based on capability registers containing large virtual addresses, using the orthogonal model for combining segmentation and paging. Together these features provided the essential base for supporting an experimental persistent virtual memory. Monads II was planned as a forerunner for the Monads III computer system.
