I resoldered the broken battery harness and it works great.  I do 
recall with my old MPROM board I owned years ago that if the 9v 
batteries were drained even just a little, it had trouble 
writing.  And it didn't take long at all to suck the power out of the 
batteries.  That was the part I hated the most, and not having a 
25-27v unregulated power supply to feed into the board instead of the 
battery leads.  I have several 12v regulated supply units, but I 
don't want to risk trashing the board by doing any experiments like 
that.  MPROM boards are hard to come by.
