I talked with my friend the other day and he claimed
that 386 motherboards all used this or that chip sets;
But I vaguely remember I might once have such a 386.
It had a 287 math coprocessor and some memory chips on
board. What I can remember is that it had many logic
chips on board but I can't recall whether it had chip
sets or not. Unluckly I dumped it years ago... Could
somebody give me an answer?

I think you are talking about one of the earliest Mylex (or AMI?) 386
motherboards. The reason for the 287 was that the 387 coprocessor was
not available immediately after the 386 introduction. I remember
evaluating such a product right after Comdex 1986 or 1987.

The brand on the computer case is either SSS or SD.
Can't remember clearly.

There was a company called CSS...but their motherboard looked very
similar to another company...I think it was Mylex.
This is all pre-Chip&Tech 82C206 Integrated Peripheral Control
(8259/8255/8237 all on one chip)

My 386 motherboard uses 82C206+82A203+82A204. I know
that 82C206 integrated two 8259s, two 8237s, one
timer(8253? 54?), and one real time. Then what are
82A203 and 82A204 for?

Yes, some early 386 motherboards did allow using a 287 FPU unit in them
... mainly because when the 386 was initially released the 387 chip was
not available IIRC. I also remember several motherboards that had slots
for a non-intel memory mapped FPU unit that used addresses above the
16MB mark to tell it what operation to perform.
I think we had a Compaq Deskpro 386 that had a 287 in it.

There were, of course, kludgeboards to replace a286 with a 386 or even a
486 without replacing the entire motherboard. I'm running one at the
moment in a PC/AT (true-blue IBM) board. Now that motherboard doesn't
have a 'chipset' as such -- it's all TTL, a couple of PROMs, a couple of
PALs (actually HALs -- the mask-programmed equivalent), and the normal
Intel support chips. So that would make a 386 machine without a 'chipset'
(one reason why I run it, actually).
I've never seen a commercial 386 or higher motherboard without a
'chipset', but would love to find one if they ever existed!

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.
