MUSASINO-1B

The MUSASINO-1 was used for computation services within the laboratory, but because it was a hand-made prototype, there were many problems with the hardware, and a great deal of labor was devoted to maintenance and operations. For this reason, the commercial MUSASINO-1B was not completed until 1960. It had exactly the same logical configuration, but it used eyeglass-type parametrons, which had been developed for practical application in electronic exchanges. The same machine was later sold by Fuji Telecommunications Manufacturing (currently Fujitsu) as the mid-size FACOM 201 for scientific calculation.
