	This short debug session will unprotect My ABC's so that it may be
be freely backed up.  The program is a cute alphabet and counting tutor
for pre-schoolers and is very reasonably priced at $10.00.  I highly rec-
ommend its purchase.  However the turkeys copy protected it with non-stan-
dard formatting and disk checking.  Unfortunately that meant I couldn't
use it for my kids, as my drive A isn't a 5.25 inch drive.  Furthermore,
if there was ever a disk that was going to be at high risk for damage,
it's the one you give a pre-schooler.  Out of necessity, then, (not 
cheapness!) this unprotect was born.

	Make a diskcopy copy of the ABC's disk and put away the original.
Copy Debug.com onto the non-functioning copy diskette.  Now enter:

	A> REN ABC.EXE ABC.ZAP
	
	A> DEBUG ABC.ZAP
	
	-E 03AF  <RET>

	XXXX:03AF  75.90 <SP>
	XXXX:03B0  03.90 <RET>

	-W <RET>
        Writing A2CD bytes

	-Q <RET>
	
	A>REN ABC.ZAP ABC.EXE  <RET>
		
	NOTES:  1.  <RET> = PRESS THE RETURN KEY ONCE.
	        2.  <SP>  = PRESS THE SPACE BAR ONCE.
	        3.  THE DEBUG PROMPT IS THE "-".
	        4.  DEBUG WILL DISPLAY THE 75 AND THE 03, YOU ENTER THE
	            90'S.
	        5.  IF DEBUG DOESN'T DISPLAY THE 75 AND 03, THIS PROBABLY
	            WON'T WORK.
	        6.  XXXX is a 4 digit hex number which varies from
	            computer to computer.  Ignore these values.

	When you are through with the above, you have a copiable, func-
tioning version of ABC.EXE.  Backups may now be made with the copy *.*
command.

	For the technically inclined:
	
	What you are doing is entering 2 NOP's which overwrite a condi-
tional jump to an exit routine.  This means that when the INT 13 returns
from the disk check with the news that the disk is a copy, the program
ignores it and continues.

	If this is of any use to you or if you have comments/criticism,
the author of this unprotect may be reached via TELSTAR BBS, San Antonio
TX (512) 822-8882.  Leave a message to ALL and mention ABC.UNP.  Again,
I recommend purchasing the program if at all possible, as it is worth
the very reasonable price requested.
