[comp.sys.apple] Clocks

GREYELF@WPI.BITNET (03/22/89)

I just received a file from Apple2-l that goes like this:

>From: matthew@sunpix.UUCP ( Sun NCAA)
>Keywords: clock date ProDOS
>Date: 21 Feb 89 14:53:46 GMT
>Organization: Sun Microsystems, Research Triangle Park, NC
>Lines: 343

>    Long ago I had always wanted a clock for my Apple //c, but didn't want
>what was being offered at that time. I ended up just settling for being able
>to set the datestamp in the ProDOS global page.  Enclosed is a small program
>with source, that when placed as the first ".SYSTEM" file on the disk, will
>allow the user to set the current date.

For those of you that have also received this file, I'll save you the
trouble of reading more than necessary.  I just wanted to say that
one of the functions of my shell program includes installing a
Prodos-compatible clock from software, based on  the 60 Hz
interrupts of a mouse card in slot four.  So if you don't want
to buy a physical slot card, use the clock  or iclock commands
under shell and one will be installed for you.

It occurred to me that the current version of Shell lacks the
TIME and DATE functions I mentioned, so since I have them
written, I'll upload them later today.

The clock routine taps the interrupts from the mouse card,
making a clock from software that is Prodos compatible, and
works just fine for dating software you save.

Is there any possible way to put a clock card in an apple //c?  Or any other
way to keep accurate time on it(background program)?

    Applied Engineering puts clocks in their ZRAM cards, and I believe they 
sell a clock separately as well.  Someone (I can't remember the name) also
the "//c System Clock", which plugs into the serial port (it has another port
on the back so you can still use the serial port...)


Hope this helps,

For the IIc, I strongly recommend the NO-SLOT CLOCK from:

                  Systems Manufacturing Technology, Inc
                  1145 Linda Vista Drive
                  San Marcos, CA 92069
                  619-744-3590

It is a device which you can install by removing a pluggable 28 pin ROM on
the IIc motherboard, plugging in the clock in its place, and then plugging
in the ROM to the clock. The only trick is opening and closing the IIc case,
but with a little patience it's manageable.  One caution: if you have
installed a memory expansion board there may not be enough clearance for
this clock.  This clock provides year, month, date, day, hours, minutes,
seconds, and hundreth seconds. It has AM/PM or 24 hour mode and corrects
for leap year.

I bought the NO-SLOT CLOCK from:

                  JDR Microdevices
                  2233 Branham Lane
                  San Jose, CA 95124
                  800-538-5000

The price was $29.95 incuding manual and software utilities for use with
DOS 3.3, PRODOS, and even MS DOS.  It can be used in IBM PC/XT/AT, Apple
IIe, IIc, Franklin ACE 2100, and Laser 128 computers.
