4c51019e30 Moved the common "read/write register A and B together as a 16-bit 
value" functionality into a read function and a write function. Also
added ability to set pull-ups.

407f6831a9 Initial import of my test code for the SIMM programmer board. Right now

and an (untested) external memory interface driver that uses it.
