- IBM_4020_Military_Computer abstract "The IBM 4020 Military Computer were Cold War computers used in the two IBM AN/FSQ-31 SAC Data Processing Systems.Details: Instruction rate : Up to 400,000 instructions per second Cycle time : 2.5 microseconds Word size : 48 bits + 2 parity bits Core storage : up to 131,072 words operates in parallel mode 69 instructions single address instructions Add or subtract : 2.5 microseconds (fixed point) Add or subtract : 7.7 to 26 μSecs (floating point) Multiply : average 24 μSecs (24 bit precision fixed point) Multiply : 5 to 74 μSecs (floating point) Multiprocessing with Automatic PriorityThe instruction format includes: 7 bit op code 2 bit real data indicator 3 bit byte displacement 3 bit mode selector 1 sign bit 8 bit 'byte activity' 1 bit Double index flag 1 bit Indirect address flag 4 bit index register selection 18 bit address.Man-machine communications included a light-gun to indicate an area of interest on a visual display unit.Circuit logic packaging was based on 7 types of Q-pacs each holding 1 to 4 circuits. Transistors and semiconductor diodes were soldered to the outside of the Q-pac encapsulation for ease of cooling and replacement.".
