[comp.sys.ibm.pc] XT clone speedup kit general questions

kahn@xanth.UUCP (Gary I Kahn) (09/19/87)

Does anyone have any comments on PC/XT clone speedup kits, such as the
Fast88 and the Nickel Express (sold by JDR in Byte)?  Should I expect
any problems with operating my clone (a Fountain XT) at 7-8 MHz?
I wrote to the Fast88 people with some questions, but that was 4 weeks
ago and they haven't answered.  They must not need any more customers.
Do most of the speedup kits also operate at the standard 4.77 MHz on
demand?  Thanks for your help.
