In other words: what would be most helpful would be an assembler listing where I can learn from how to set and readout the NSC. Is there any resource available online where I could have a look at?
Thx,

I have a NoSLotClock, and the manual have ASM listing to show how to
check if there is a NSC, how to set it, how to read it.
Let me find it.... Wich could take some time.

Well, last year John Brooks posted here saying that he wanted to write another NSC driver. Perhaps he'll reply here with a more complete example, or you could email him.
In the meantime you could look at the partial disassemblies I did of the (known) existing 3 drivers when I was writing the NSC emulation for AppleWin.

Cheers,
Nick.

I wrote an NSC driver for ProDOS 2.4.x last year, but there were compatibility issues with some CPU accelerator chips/boards.
After VidHD launches, I plan to rewrite the ProDOS clock drivers (NSC, GS, Thunderclock, etc) to support a new 4-digit long-date format. IE fix the pending Y2030 problem in ProDOS.

Look forward to it. NS.CLOCK.SYSTEM doesn't run on a ][+ either (for me).
