Pinouts for MAKE TRAX (Williams, 1981)
Submitted by firstname.lastname@example.org / 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.
