I attempted to port the same version of unix to an
rl02 disk pack and
to run on an actual 11/40. I was able to get ir to boot up to the #
prompt but my system does not have a working EIS card to proceed any
further.
I"m incredibly surprised that you got to the prompt! First, the V6 RL
bootstrap uses ASH, part of EIS. And then the C compiler makes extensive use
of EIS instructions, so anything in C (the OS, 'init', 'sh', etc) may have
EIS
instructions in it.

Those were your directions I followed from your web site (somewhere don't
remember where)! The disk pack boots I just can't do much more than hit
enter and cause another # prompt, maybe get a command not found message.
It has been a while. I built the image in simH first, then ported to a
real RL02.
