Actually my problem with the Supnik emulator is that the clock runs
_very_ fast - the "PDP11" ends up being hours ahead of the real time
after recompiling a kernel or two.
p11 on the other hand tends to run slow - tweeking the device.c value
was aimed at speeding up the clock.

With a change to 'geni.c' or by editing the instab.s file?

Yep - that's what I was seeing until I regenerated the instab.s file
by running 'geni'. The emulator would compile and link with a
manually edited instab.s file but simply would not run correctly.
Since the same RP06 image worked with the Supnik emulator I knew it
wasn't in the 2.11BSD area.
