Hi,
The very first EISA machines were brand new in June of
1989,
and were powered by 25 MHz 80386 CPUs....
Yes, there were a fair few '386 based EISA motherboards on sale here in the UK
around 1990. '486 based ones didn't appear for a while after that - a year or
so ISTR.
That said, AFAIK the first EISA based _SYSTEM_ to hit the market was HP's
"Vectra 486". It's reviewed in the November 1989 issue of "Byte"
(page 93, the
magazine is no more than 6" away from me as I type).
....I used to have a copy of the Byte in question,
which also
featured MCA clones. I wish I knew where it got to.
Hmm, I don't think it's quite the same issue you're referring to (no MCA
clones), but as I said above I have the November 1989 here. It's a handy one
to have around as it has a reasonable technical article in it about the EISA
bus....I actually use it as a reference for the pinouts of the ISA bus of all
things.
I've got most of the issues of "Byte" from 1988 through to 1994(ish) here,
I
could try and dig up that article on MCA clones if you want?
TTFN - Pete.
