Well the board is clearly marked for power and what the wires are for
but I don't know what the output is.

This is a pic of the terminal board. Wires 1-8 go to the encoder. The
bundle of wires in the center leads to the input-output connector for
the motor/tach/encoder assembly. The encoder itself has two wires
marked A and B ( number 6 and 7 on the board) but the other wires are
also connected. After hooking up power to the input on the encoder I
put my fluke in frequency mode on the 6 and 7 to ground and picked up a
count as I turned the shaft. Things look good.

The connector on the left of the board is for the limit switches. One
of the switches is broken. Is there anything specific about the
switches other than taking into account the environment they operate in?
There also seems to be an optical setup for limit switches in the
tables. I'll see if I can figure out how these work and do away with
mechanical switches.

Geckos are ordered and should be here next week. We'll see what
happens. I'll have to decide on a control software before then.
