486 Turns 15 Years Old

wooby writes "The 486 processor , introduced in 1989 at 25 and 33MHz clock speeds, is now 15 years old. Intel's simultaneous launch of both the 486, a CISC chip, and the i860, a RISC chip, was a gamble. Remarks Intel's former CEO, Andy Grove: 'our equivocation caused our customers to wonder what Intel really stood for, the 486 or i860?'"

      AT&T built and shipped the "AT&T PC", which actually worked that way. It didn't sell, but it did work. It was just like running UNIX on a PDP-11.
