   Sorry, the XT is an 8088 running at 4.77MHz just like the original PC,
and has the same 8-bit external bus. The primary difference is that it has
eight slots instead of five and came stock with a hard drive.
   IBM never made a faster XT. Cloners did, but they still had the 8-bit
external bus.
   When the 286-based AT came out, IBM did produce something called the
XT/286, which was an unholy combination of the XT and AT but not really
quite enough like either. Not many sold.
