Pinouts for MAKE TRAX (Williams, 1981)

Submitted by shu@cco.caltech.edu / essayes@telerama.LM.com

Here are the Make Trax pinouts, as promised.

Unfortunately I can't confirm it's 100% correct, as my board has a bad 
RAM so I couldn't test any of the switches.  At the very least the video
and power contacts are correctly identified.

Like I mentioned, the board is not the big multi-unit Williams setup used 
in Stargate, Robotron, etc.  It's a single board, kinda small.
