[cctalk] i860 vs. i960 WAS Intel's i860, Cray-On-A-Chip

I always thought the i960 was an upgrade to the i860 (sort of like i386 to i486 upgrade). However, based on the info on wiki it seems as if the i960 actually came first and although a RISC chip it was in no way in the same league as the i860. Anyone can clarify or verify this? -Ali
