FACOM 128
Japanese relay-based electromechanical computer
From Wikipedia, the free encyclopedia
The FACOM 128 was a relay-based electromechanical computer built by Fujitsu. Two models were made, namely the FACOM 128A, built in 1956, and the FACOM 128B, built in 1959.[1] As of 2019[update], a fully working FACOM 128B is still in working order, maintained by Fujitsu staff at a facility in Numazu in Shizuoka Prefecture.[2][3]
The FACOM 128B processes numbers using a bi-quinary coded decimal representation.[4]
