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)?

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...)

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. Rich McAllister McAllister@DOCKMASTER.MIL
