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?
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.
