Thanks.

It has been reported that Solaris 2.5.1 does work with the 604e, which the 7043-140 has, so I will be looking for another box to run 2.5.1 PPC on.

I worked for Sun on Solaris back when the PPC port was done (and work for Oracle now on Solaris). I asked among Solaris folks (current and former) about PPC compilers and “possibly gcc 2.95 otherwise cross compiling” was suggested.
