386 motherboard with discrete logic chips only?

Heck yes!

I was envolved in the development of a 386SX-16 motherboard that
used no VLSI chipset.

It did use a large number of GAL's however. It drew an absurd ammount
of power compared to any chipset on the market back then, but it also
outperformed all of them, due to a decent 2-way cache design.

NEC produced and sold this motherboard. I was given one of the later
prototypes, and use it as my PC for a time. Then it hung on my wall as
a trophy for a time, and then was shipped overseas to my Father in law, and
he ran it for a long time. I'd asked that it be returned when it was
obsolete
by overseas standards, but alas it was lost.

But never the less, not all 386 motherboards used VLSI chipsets.
