Speaking of which, I read in a PC repair book that the 486SX is a
486DX with certain lines cut to disable the math coprocessor. The
thing that went into the coprocessor socket was a rebranded 486DX
that took over all functions of the SX when installed. Anyone know
about this?
that's
the
bus

Yes, to say that the 8088 and 8086 were the same is incorrect, but they
_basically_ had the same core and everything... it was just the data was 8 bit on the 8088 and 16-bit on the 8086. They were
fully
compatible
program-wise, just that the 8086 was faster as it could
push 2x data
over
the 8088.
Comparing the 80386 and the Pentium wouldn't be fair, tho. Comparing
the
80386SX (with the 16-bit data bus) and the 80386DX
(with the 32-bit
data
bus) would be a lot better comparison... as again, the
chips were fully
compatible, but the DX's were faster due to the larger data bus.
Just the way I seem to remember it...
