FWIW I found that option 1 is the Alpha-numeric printer. Option 4 is 256 registers of
memory. 256 registers can hold 2048 instructions, the standard memory can only hold 512
instructions. I can't find a listing of options PA and PB, does anyone know what
they are?

Top this: Not one, not two, but THREE Tektronix 31 calculators, all NIB!
Found these at a garage sale. They appear to be from the estate of a Tektronix employee
that bought them in Beaverton and shipped them to Orlando when he was transferred here.
Two are "normal" 31s, the other is a different color and is marked "Coulter
Model 43 Data Converter". It has options 1, 4, Pa and Pb installed. I've posted a
couple of pictures of it at <http://home.cfl.rr.com/rigdon14/tek-31/>. I haven't
checked out the other two yet but they also seem to be well optioned out and have what I
think is the interface to connect the TM500 modular instruments.
