Chip Directory: has useful data on chips and may help identify some. Mainly data about exotic chips that is difficult to obtain elsewhere. Also most CPU's including the Zilog Z80 for example, used by Sir Clive Sinclair's ZX81 [first] microcomputer, and the Motorola 6802 used by the early Apple II microcomputer. Plus a special Soviet section. Soviet chips are just as good electrically, but much cheaper. They do the CMOS and TTL series for example. Related BAEC articles:
