SWTPC SuperClock II board

[Doug Jackson]

That's a beautiful board.

While I have no docs, a careful look confirms for me that it would
superimpose something (likely clock data) on a video signal.  The
horizontal and vertical counters, mux and Rom give that away.

I love the layout.   Absoloutly done in the days of tape ar 2 or 4 times.
  Beautiful.
