"Computer Chip of the Month"
Toshiba TOSBAC Computer CPU chip
For the month of October we are featuring this CPU chip used by Toshiba in later Microprocessor based models of their TOSBAC (TOshiba Scientific and Business Automatic Computer) line of Japanese computers.
Toshiba's first entry into computers was in 1952 with the start of the Toshiba Automatic Computer (TAC) project at the University of Tokyo - an early vacuum tube computer with cathode ray tube memory. Toshiba's first commercially available computer, the TOSBAC 4200, would be announced in 1961.
