Oh yeah, without that, you're totally hosed, Unix-wise. The V6 C compiler
puts out MUL etc all over the place (e.g. for structure pointer math), so
there's absolutely no way to run vanilla V6 Unix without it.

(The GCC compiler claims to be able to compile C to machines without the
EIS; it might be an interesting hack to see if that could be used to get
V6 running on a machine without the EIS. The machine language startups
would still need work, though. And the bootstrap. :-)

Right, but if his bootstrap isn't working, gotta debug that first.. :-)

Actually, I don't think you need to re-compile anything, just link in m40.o
instead of m45.o; I think all the C code checks for 'cputyp == 40' or
whatever, as the case may be.
