strange number corruption on pdp11/34

...and the same routine with the 'good' KD11E-A.

 Note that it has proper console emulation numbers with real values and no
missing digits at power on.  Also, I don't have to halt the thing and enter
165200 to get it to talk to the console - it does it happily itself. ZRLG??
offers sane defaults and gives real pass counts and numbers in output.
Note also that rsx boots and starts up happily.

What can I say?  That other board was just a pretty messed up processor :\

I'd like to fix it, but have no clue where to start.
