Abstract
PSI is a personal computer system being developed as a tool for providing researchers with an efficient programming environment. It directly supports logic programming language, KL0 (Fifth Generation Kernel Language, Version 0), with firmware and hardware.
Its interpreter is implemented in the firmware and several hardware mechanisms are provided to attain almost the same level of performance as the DEC-10 Prolog on DEC2060. It also provides the user with a large memory space, 40 bits × 2 to 16 MW, which is essential for developing actual application programs like an expert system.
To make efficient man-machine interaction possible, such input and output devices as bit-map display, pointing device and key-board are provided. A local area network is also being developed to build a distributed system.
