I've written a Venix/86 userland emulator. It uses
FreeBSD's vm86 to run
binaries natively and intercepts traps for things like system calls. I
finally have it to the point where it can run the compiler via cc (which
forks and execs c0, copt, cpp, as, ld, etc). My plans to try to recreate
the sources for the binaries for Venix/86 from V7 and other extant sources
have taken a step forward. Don't know if I'll ever get there, but at least
I don't need a working Rainbow and can run the compiler at ~4GHz rather
than ~4MHz....

I wonder if an approach like this could work for Venix/PRO.
