SWTPC SuperClock II board

[Kyle Owen]

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!
