...A bit off topic for the 'FPU card' side of it, but AFAIK the expansion slot on the Classic II also handles the external ROM slot as well (up to 1MB IIRC).
If you're designing a board at all, why not include the potential future ROM upgrades by including a ROM socket as well?
I'd love to see a "IIsi" style ROM for the CII in the future...
