Hi Michael,So a NSC *is* already used (at least indirectly via ProDOS) by the cc65 C library.Good! :-)I agree--a very appropriate way to deal with time().:-)The con's: - No secondsNot so good! :-(IIRC, the seconds are available in the $200 buffer at a well-known ;-) location after a time call, depending on the particular clock driver.Yes, bu the whole idea of implementing time() based on ProDOS was to abstract from the actually used clock hardware...
I wasn't suggesting that you use this information, but that the OP might find it useful, since he presumably has some specific clock, together with a need for precision timing. ;-) -michael NadaNet 3.1 for Apple II parallel computing!
