It was a IIsi, but you get the basic idea :)

All the Apple-brand IIsi NuBus adapters have an FPU. I don't know of any
that weren't made by Apple, but I suppose it's a possibility. You can use
any 7" NuBus card in that adapter, and some 12" cards, but you may have to
find a thinner hard disk to use a card that long.

Those were mostly used in case Apple found an error in the production ROMs
and wanted to patch it later. That's why the later-model IIsis don't have
ROM SIMMs and why some later-model IIcxs don't even have ROM SIMM slots,
just solder pads.
