What does the ROM\FPU do?

When I opened my Macintosh Classic II, I noticed that it had a ROM\FPU Chip. What does it do? Does it help processor? If you have info please tell me. Thank you.

ROM essential, FPU helpful

ROM - Read Only Memory. The computer needs this in order to function.

FPU - Floating Point Unit. This chip allows the computer to do certain calculations much faster.

I don't know much about the details of the Classic II's motherboard design, but I'm surprised to hear that it has the ROM and FPU on a single chip.

IIRC, it's actually a riser card that houses the FPU, additional RAM slots, and optional ROM chips to expand what is on the motherboard.

Thar be a slot!

Yeah, the Classic II has an internal PDS-type slot to allow ROM updates/expansions or an FPU to be attached. AFAIK, only an FPU was ever made for the slot, and they're rarer than hen's teeth.

Then maybe it's a good thing I've got one, and a C-II mobo with no video...
