Oregon State University has designed and constructed a medium speed, serial digital computer using glass delay lines circulating at 22 mc. as memory. The design objectives as originally conceived in a special seminar were 1 To be a research project in computer design. 2 To be used as an educational machine. 3 To have easily modifiable hardware for basic research in computer systems design. An unusual arrangement of information within the 22 mc. memory allows a simple interface with the 340 kc. arithmetic unit, which results in an effective zero latency time and provides possibilities for an associative memory. The arithmetic unit has a command structure similar to large parallel machines and uses flip-flop arithmetic and control registers throughout. All hardware development has been aimed toward the concept of easy modification, elaborate console controls for effective man-machine interaction, and low cost. This report describes the status of the project as of August 21, 1967. Author
