A VAXstation 3100 series GPX (VS40X-PA) controller is supposed to have
a resolution of 1024 by 864 at 60Hz while the SPX (WS01X-GA)
controller is supposed to have a resolution of 1280 by 1024 at 66 Hz.

The color video cable 15-pin D-shell to 3-BNC cable for the SPX is the BC23J-03.

The keyboard is the common LK201.

I installed OpenVMS 7.3 on my VAXstation 3100 M76 SPX.
