I have a co-processor with this text printed on it:
Super Math Chips
J38700DX
T9M06A
9142-A

It seems to be a 80387-proc
When I plug this coproc into my motherboard, the bios recognizes it.
But the system becomes very unstable (floating point-errors, stack underflow and overflows...), even my soundcard drivers gives an error.
When i run Nortun Utilities System Information it says that te coproc is a Non-intel 80287.

Is it a 387-proc or not?
becom all systems whit a optional coproc unstable if you use them?
Will my system unstable if I use a real Intel 80387 ?

Sorry for my bad english

I have one 386 with an INTEL processor and a CYRIX coprocessor.

It works fine. I guess I couldn't give you any more info than that since none of my other 386s have coprocessors.

I have had a few other computers, mostly 486s with coprocessors which also worked fine.

Good luck
