In the whatinthehellisthat department:
I have a small daughterboard, pulled from an very early Sun SPARC machine
(perhaps the first generation Sun-4 architecture). The floating point chip
was replaced by this daughterboard. On the daughterboard is the PACT8847
chip (the normal floating point unit), plus a larger chip called
100-1845-1 SUN-GNUFPC. The daughterboard seems to be called GNUFPC COBRA,
and seems like real Sun hardware.
"There were two types of FPU used in SS2's, the Weitek 3170 (
used in most machines) and the GNUFPC/TI8847 (used in some early
machines). "
