Identify HP board?

I've found an HP board, which has "HP 03812L" and then "98574-66513" on it. I think this is a part for an HP9000 system, more precisely a "68040 EMULATION PROCESSOR". Is this something you can plug in in place of a real 68040, and if so might it work in anything other than an HP9000? It sounds plausible, since it has an SC140475RC50 (looks like some kind of processor?) and an XC68882RC50A (FPU) on it, as well as an MK4202P (eh?), some fast logic, some cache RAM, and a 184-pin "plug" that obviously plugs into something like a processor socket. I was given it for the 68882, for use in a Mac, but I'm wondering if it's better left intact... BTW, anyone know the difference between an MC68882 and XC68882? -- Pete Peter Turnbull Network Manager Dept. of Computer Science University of York
