2.5 MHz 40-pin ceramic DIP Very rare version of the Zilog Z80 processor in white ceramic package. Z80 microprocessors were released in July 1976 (May 1976 according to Federico Faggin's www.intel4004.com website). Production date of the chip on the picture is 23th week of 1976 (end of May or beginning of June) - one month before the CPU family was officially released or a few weeks after that (if the May 1976 introduction date is correct). |

Zilog Z80 Dallas CPU
The Picture of the Zilog CPU you have there was made at Mostek. Mostek was a second source for the Z80 CPU family. I know, I worked there from 1976 to 1983. Just go to wikipedia and lookup Mostek.
