The original K6-2's off the line where all 100MHz parts, it was later when
AMD found that some people where sticking these in 66MHz boards and trying
to run them with a 66MHz FSB and having troubles that AMD started to test
the parts for 66MHz operation, they had to make some changes in the I/O
buffers and then qualify a new part number and those are the ones stamped 66.
Aka AMD 6K86-2-P300/66 vs AMD 6K86-2-P300/100 for those who know what a
real AMD part number is.
To the best of my knowledge no 0x580 stepping 0 chip is qualified by AMD
to run with a 66MHz FSB.
