Hi,
Were there ever 8086 to 80286 upgrades for the
few machines that used them?
There was at least one available. I had one in my first PC clone, a home
built machine with a motherboard sporting an NEC V30 processor (NEC's clone
of the 8086).
It was a 1/2 or 1/3 length 8-bit ISA card from which ran a (very) short
cable which plugged into the processor socket on the motherboard (the 8086
was removed and plugged into the ISA bard). There was a switch on the back
plate which selected "normal" or "286" mode.
I don't recall the manufacturer, but "AST" rings a bell for some reason? I
got it in late '90/early '91 and it was at least a couple of years old then
I think.
Didn't use it much....LOL.
TTFN - Pete.
