...which is a feature unique to the PDP11/05 and 11/10.  The odd thing
is that the PC increments by 1 in this case, so you can use all 6
general registers (not the PC of course -- but registers 0 through 6,
at address 777700 through 777706 can be used for small test programs.

(See also the PDP11 trivial quiz...)
