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.

Subject: SWTPC SuperClock II board
In the midst of cleaning up, I came across this board. Can't seem to find
any info online about it. There's another board from another company, not
SWTPC, with the same name?apparently a timekeeping board for an Apple II.
I assume this is a way to generate a composite video signal with the
current time displayed? Anyone have schematics or a parts list?
Thanks, and stay healthy!
