I have a S100 board made by N* that is a math board

doesn't have a FPU. It has a 2901 and some ROM chips.
It only has the one 2901.

That is the same board that I was talking that kicked off this
mini-thread. However, reading back, I wrote it a funny way:
Northstar (of Northstar Horizon fame) sold an S-100
card that had
a TTL FPU on it. It was a microcoded affair (256 words of 40 bits) ...
I meant to say the board implemented a FPU in TTL, not that there was a
monolithic TTL FPU chip of some kind.
