I’ve been trying to chase down something usable from CMU Mach for way too long. I think
the afs project is largely on auto-pilot for the last 20+ years, and whatever is
accessible is, and whatever isn’t is either lost or locked up with accounts that have
moved on in one way or another.
The only sizable release of Mach of the era is on the 4th CD of the CSRG releases. And
it’s far from any buildable state, that I could really see.
Forever ago there was an effort to get Mach 4 + Lites running and I did get it running
kind of by accident. I never could rebuild it from source. Maybe I’m just missing
something. But it’s not intuitive at all. I guess it’s like the MT XINU Mach for the
i386, basically it was a thing but no copies seem to have survived.
I guess IBM would be scared of people seeing either RS/6000 or the prior ROMP/RT
architecture code, and people running their own OS’s. Much like the MacMach port. I
tried asking the MachTen people about buying their source but they only have binaries on
CD.
Probably not the reason, these machines were fully and publicly
documented. In fact, there is still a book in print on the ROS
residual data and firmware runtime services. Most of the register
info was in "Hardware Technical Information" manuals that were
publicly ordered from IBM Publications (I have these). And in fact I
provided this info and it was used to bring up NetBSD in the mid
2000s.

Does anyone have these documents or the ports themselves? Or know who
to talk to so they can be preserved?
