[net.micro.apple] Timing on apples

ed@gargoyle.UChicago.UUCP (Ed Friedman) (12/08/84)

     Does anyone know of a way to get detect real time from Apple II
computers without buying a clock board?  Is there any memory location
which steadily increments on some fixed cycle?  I know that a time delay
of x seconds can readily be programmed in, but I am concerned about a
program with numerous levels of interrupts which still can refer back
to some subroutine which will return the real time.  Has anyone done
something like this on the Apple II?  If so, I would like to hear how
you did it.

                                     Thanks in advance,
