Has anyone had any experiences (good or bad) with accelerator cards on
either 8088 or 80286 machines? Do I have to use faster RAM than the
board had on it to start with? Can I really expect the speedup
the ads say? I have a 286 clone I'd like to boost a little as well as
an 8088-2 XT clone that could use a little shot in the arm too.
Thanks so much. Warren

Therefore I posted my reply here... ----------------------- 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! PY -- Peter K.H.
