 Ok, how about a 9511A or 9512 math co-processor
chip (Intel 8231A or 8232)?
The Intel web site has info on the 8231A only.... 
Part of the difficulty with many of these parts is that they were
so expensive in the first place, that most designers found some
way of avoiding them.  The 9512 that I own, for example, cost over
US$200 when it was purchased as an option with the Compupro
System Support 1. 
Ouch...$200 in the early 80's was a fair amount of money.  I can see why
designers would try to avoid utilizing it if at all possible.

According to the Intel web site, Rochester Electronics has been licensed to
produce many of Intel's older NMOS chips.  The news release used the 8231A
as an example.  I haven't browsed the Rochester site lately, but as of several
weeks ago, the chip didn't appear in their inventory.  If offered for sale,
wonder how much they'll charge?
