V7 doesn't run. More precisely, it boots and
starts the kernel but it
immediately panics. I can't remember what the message was; it's a long
time since I tried it.
I've seen this too but I got it going (late) last night.
I think it was with the E11 simulator and I set the
CPU to "70" (or maybe 45). It boots to the "#" prompt.
If you exit it starts timesharing. The root password is
"root".
