   I'm not sure about the Sun 4/110.  Is its FPU a board option?
   Maybe it used to use earlier Weitek chips, but now uses TI's data path.

The 4/110 and 4/260 were shipped long before the 3170 was a gleam in
anyone's eye ... FPU1 (or just FPU) was a Weitek
1164(adder)+1165(mult)+sun glue. It was unfortunately an option for
the 4/110 (but this sans FPU option was not very popular, for obvious
reasons).  

Early in '89 FPU2 was made available as an upgrade for units already
shipped, and made standard for new orders. FPU2 is a TI8847+sunglue.

FPU2 is what is employed in the 4/330/70/90 and 4/490 machines.

The 3170 is what is customarily employed in the 4/60. It was designed
to be a SPARC FPU so there is no glue needed.
