Solaris 2.5.1 PPC doesn't work on that machine.
I can't find the HCL doc, but according to the files present on the CD it
IBM 6040 (ThinkPad 820)
IBM 6042 (ThinkPad 850)
IBM 6015 (PowerSeries 440, 7020-40P)
IBM 6050 (PowerSeries 830, 7248-43P)
IBM 6070 (PowerSeries 850, 7248-43P)
IBM 7248 (43P-100, 43P-120, 43P-132)
Motorola PowerStack Series DT/E/MT
The 7248-43P is substantially different from a 7043-140 "43P". I have it
running on a PowerStack Series E.
Did anyone ever unearth the Sun compiler for that?
