I never got too excited about the '386 adapters to
a '286 system, because
the 386DX was a mite slower than a '286 running from the same clock. What's
more, when you used a '386 back then the first thing that the OS did was
tell it "you're a '286 now" and proceed. The '286 did this a little
better.
By the time there was a '386 that actually outran the '286, ther was a '486
that could outrun 'em both.
Thats good to know, mostly I think what I would like to find are the 486
upgrades to 386 based machines. Many of my "cute" computers are 386 based,
and the added speed of a 486 might be nice in some situations.
