BTW, Intel didn't call the Pentium the 80586, or the PPro the 686, so I don't either. If somebody wanted to argue that [all] Pentiums are not x86s, that's fine with me, because their chip numbers do not end in 86. If somebody else wanted to argue that Pentiums ARE x86s because they only run x86 code, that's also fine with me. My problem is when somebody calls the 8080 an x86 even though its number doesn't end in 86 and it doesn't even run x86 software. I mean, really, what POSSIBLE reason do you have for calling the 8080 an x86 besides the fact that they're related enough architecturally (in your OPINION) to be considered part of the same "family." I can imagine you marching into BMW headquarters and arguing with them that the BMW 2002 was the first 3-series because in your OPINION they were related enough that the 2002 should be grandfathered in. -Tom
