-----------------------

I am using a BreakThru-286 card in my XT clone. You do not have to upgrade
anything to use that card since it uses a 16K cache to cache your standard
memory. The only catch is that it only works in the standard speed (i.e.   
4.77 MHz). If you have a 'turbo' motherboard, you have to jump it to boot at
the standard clock rate.

I have the 8MHz version and switch the 16MHz xtal to a 20MHz
xtal to make it runs at 10MHz without any problems. Almost all benchmarks
I tried reported that it runs faster than a 8MHz AT (typically 10% faster).
The card is very reliable and there is no problem with compatibility except
with programs using timing loops (those programs won't work in ant 10MHz 286
boxes anyway).

Regards!
