Message-ID: <3002@crash.cts.com> Date: 5 Jun 90 06:36:01 GMT Sender: root@crash.cts.com Organization: People-Net [pnet01], El Cajon CA Lines: 18 I was digging around inside my xt-clone tonight and was trying to find the locations of the various chips. I Know that the microprocessor is the 8088-2 but there was a chip next to it with the following on it: NEC 8643w5 V20 D70108c-8 '84 NEC Now from this I know that the chip was probably made in the 43rd week of 1986 and that NEC is the manufacturere. But I was wondering is this a Math Co-Processor?? I have heard of the 8087's but this one is not one that I have heard of. Any info on this chip would be a great help.
