This is substantially crazy :-)

IIRC the mechanics were kind of sticky when new.

The whole "changing flip-flops" thing really took me back.  I learned
to do that in high school on our Control Data G-15.  The multiply
instruction was the first to go :-)

I kept it running for some time using that method.  (of course we did
not have a budget to order spares)
