  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.
