Ayuh. Glad I'm not the one to do it.

Adam Fritzler appears to be the smart guy regarding the confluence of MCA
and PPC. Though he's pretty heavily loaded with Token-Ring issues, IIRC.
I suspect technical (HW- and register-level) docs for any PowerPC MCA
RS/6000 boxen would do it. But I don't know who should get it.
Someone with time, C skills and the appropriate hardware COULD raise their
hand and describe their platform(s)...
MCA platforms I've seen so far on LPPC-WS (dupes are likely):
RS/6k 250
7011, 7012, 7013 PowerPC models
PowerPC 42T
RS/6k Mdl C10
It would seem like the best tack would be to go after the MCA PowerPC
boxen with an MCA port and a bootloader. Once that's working one could
then start playing with POWER's different MMU and instruction set.
Someone said that the PowerPC compiler can generate POWER code.
And I counted about 5 people with boxes expressing serious interest
in running Linux.
I don't count, as I don't kernel-hack or own any IBM RISC hardware.
BTW, any word on those PPC IBM NetFinity boxen's hardware?
