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

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!
