So what was 4-bit about the Central Air Data Computer?

From a quick look at the architecture paper for it, it had 20-bit floating-point numbers and 20-bit instructions. It may have come out before the TMS 1000, and thus be considered "the first microprocessor", but that's not particularly relevant to a page discussing 4-bit processors in particular. (It also was a multi-chip microprocessor, so the TMS 1000 remains the first single-chip microprocessor, as the article says.) I'll remove the information about it from here unless somebody can come up with a good reason to include it. Guy Harris (talk) 22:53, 20 July 2013 (UTC)[reply]
