I was looking up the "first" 32 bit CPU chip. Ummm, 1980 is before 1982 https://en.wikipedia.org/wiki/HP_FOCUS The Hewlett-Packard FOCUS microprocessor, launched in 1982, was the first commercial, single chip, fully 32-bit microprocessor available on the market. [I guess "fully 32 bit" is the key phrase: 32 bit external interface?] https://en.wikipedia.org/wiki/Motorola_68000 The original MC68000 was fabricated using an HMOS process with a 3.5 um feature size. Formally introduced in September 1979, initial samples were released in February 1980, with production chips available over the counter in November. Once again, "Who Was First" is a vague and dangerous question. I'd love to see a "Who's On First" variation about "first" computers, with ENIAC on first :-) I agree with defining a focus for the CPU exhibit. Certainly the 8 bit processors are a natural grouping. Or just the processors of the 70s: https://en.wikipedia.org/wiki/Microprocessor_chronology
