I'm not sure if 12 MHz parts are sufficient; we put 16's in our 3/50's. I
think there might be a jumper to select which coprocessor clock speed you
want, but I'm not sure. /usr/etc/mc68881version reports that ours are
running at 16 MHz.
But, assuming it's 12's that you really do want, I noticed that they are
in the Jameco catalog! They list the XC68881RC12A for $54.95, quantity 1.
If I understand their part number code correctly, it's an XC (as opposed
to MC) because it is "close-out pricing -- part number will be
discontinuted when stock is depleted" Try calling them at 415-592-8097.
