Weitek 4170 math coprocessor socket

WTL 8601 SPARC POWER µP
WTL 8701 SPARC POWER µP, internal bus speed doubled

Weitek 8200 RISC processor, based on HP PA-RISC
Weitek 8200, 7.25 MHz embedded processor (e.g. used for Apple LaserWriter Pro 810)
Weitek 8220, 16/20/25MHz RISC processor

Most Weitek chip versions do not support DOUBLE PRECISION computations.
Use of single precision computations with the xxx387 coprocessor is not successful.
