Do they really hang, or just sit waiting? I've never used 2.9, but 2.11
normally waits for you to type CTRL-D at a critical point. 7th Edition
just prints an "_at_" prompt from a hardware boot, and waits for you to type
"boot" (which gives you a "Boot:" prompt, to which you'd normally respond
"rl(0,0)unix").
Does 2.9BSD really fit on an RL02?
If they really do hang, it's possible you've run foul of a bug in the
emulator - older versions have a bug in the floating point, though I'd be
surprised if that affected booting.
