Another option would be a compiler that generates no-FP code. That's faster than
emulation. gcc can do that; does 2.x BSD cc have such an option?

Depends on the UNIX. Ultrix works fine, and the latest patchlevel of
2.11BSD has floating point simulation that works fine.
(I'm running my 11/70 sans floating point hardware at the moment, I'd still
like to find a boardset one of these days, though. Floating point
emulation is slow!) I think the FP11 boards are not essential for the
11/70
They only add hardware FP support.
Not essential for many uses, but I'm pretty sure UNIX is unhappy
without them. If you are going to run RSTS/E or RT-11, should be just
fine either way.
