<I didn't put the 386 in the XT socket. I just pulled the clock xtal from
<386 and put in in the XT. It wasn't a real IBM PC, it was a clone.

Bit more believable. A 25mhz crystal used on the 8284a nets 8.333 at the
processor clock input and that would make a XT-turbo. The problem with
such a speed up is that the peripherals and the ram have to be faster as
well to keep up.

I have a Leading Edge Mod D that I've tried that on and 6mhz(18mhz
crystal) was possible before needing to add wait states for IO and
memory. With one wait for both IO and mem 8mhz was doable. I wasn't
overclocking the cpu as it was a 10mhz V20. I may add at 6mhz the
average 8088 was likely to still be there as they were good for a shade
over 5mhz for the slow parts.
