A (nearly) machine independent software system for micro and mini computers

Abstract

UCSD PASCAL is a complete interactive software system for small computers, yet it offers many features normally found only on medium and large scale machines. It is designed to operate, with minimal adaptation, on most micro or mini computers based on 8-bit bytes and/or 16-bit words. Supported versions are available for use on machines based on the Digital Equipment LSI-11 or other PDP-11 processors, and on the 8080 and Z80 microprocessors. Having first been sent to users in August, 1977, the system is now in use on approximately 60 mainframes using these processors, and the list of users has started to grow rapidly.
