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.
I would bet that that board increases the resolution of one of the early SWTPc
terminals. I'm not sure which one.
