   Planning stages for a new plugin for my Tektronix 5110
   mainframe oscilloscope. I have traced all of the pins on the
   card-edge connector from the (ample) technical documentation
   and think I know enough to have a go at a custom Y axis
   plugin and _maybe_ an X axis one.

   The connector which matches the specification for this
   1970's scope is actually obsolete (shock!) but it looks like
   it's physically compatible with the JAMMA connector used by
   arcade machine enthusiasts and readily available on eBay. I
   have two finger boards and sockets coming from Markham,
   Ontario.
