   I just received an ad for a similar product.  It's the BULLET-286
motherboard.  It will replace an XT motherboard (XT only), and is available
in either 6 or 8 MHz versions, both with no wait states.  It traps and
emulates 8088 instructions not compatible with the '286, duplicates the
pc/xt expansion bus, lets you use your old keyboard, ...   It installs
"in under 10 minutes using only a screwdriver."  There is a
30 day money-back guarantee.  This board is apparently from Wave Mate Corp.,
but the ad I got was from UNISOURCE Software Corp., 71 Bent St., Cambridge,
MA  02141.  (617)491-1264.  They say you have to call to get the price - and
they want volume purchase and will give an "agressive price" based on this.
