I have an Everex 286 accelerator board in my machine (a switchable Kaypro XT 4.77/8MHz). The machine's CPU performance was drastically improved. Everex states (at least a year and a half ago) that it might not be compatible with all clones. My friendly neighborhood computer store let me test it out to see if it worked properly before I bought it. >Anybody have postive or negative experience with either >of these? Any others to recommend? What about 386 boards? I installed the INTEL 386 board w/ one meg of memory in a IBM PC and IBM XT. WOW! If it wasn't for the bus limitation it would've been faster than some of the IBM AT's. A year ago this board cost $600. >I want to minimize the amount of messing around with my >current system so I'd also be interested in the effort >to make the board work.

I suggest that you scrape the accelerator board idea and buy a new motherboard. I'm not sure about the accelerator board prices but you can buy a NEW 286 motherboard for > $200 and a NEW 386 for > $600. This would be cheaper or the same price as an accelerator board. It's also the best solution. Would you rather have a porche with or without flat tires? Get a new motherboard. Jameco (advertise in almost every popular PC mag) have some nice low priced motherboards. The only thing you would need in addition to the new motherboard would be a new disc drive controller. With the 286/386 machines, usually one controller controls both the hard drive and floppy drives. OPPS! You'd also most likely need new memory for the board but still, buying a NEW motherboard is your best bet. >Dennis R.
