REAL TIME CLOCK EXPERIMENTERS KIT


Copyright (c) 1988 by Nerdworld (tm) & J. R. Casey Bralla




PURPOSE
-------


This tool-kit lets you experiment with XT-style battery
backed-up real time clocks. With this tool-kit, you can
locate the real time clock registers and write programs to
set or examine them as you desire. There are programs
written in Turbo Basic that let you examine and/or modify any
I/O location, as well as quiz DOS on the current time and
date.




CAUTION:


SEVERAL OF THESE PROGRAMS WRITE DIRECTLY TO SEVERAL
I/O LOCATIONS. IF THESE LOCATIONS ARE NOT THE
CLOCK REGISTERS, THIS MAY HAVE DISASTROUS AND
UNPREDICTABLE RESULTS. DO NOT USE THESE PROGRAMS
UNLESS YOU HAVE FIRST CONCLUSIVELY DETERMINED WHERE
THE CLOCK REGISTERS ARE LOCATED. THE AUTHOR WILL
NOT BE RESPONSIBLE FOR ANY DAMAGE OR LOSSES
INCURRED AS A RESULT OF USING THESE PROGRAMS.
