Well, it is sooner than I thought.  I found the CALL for the copyright notice.
The fix that I am going to give is for the '*' version of 1A.  In the notice
it says 'Release 1A' and right below that, centered, is a '*'.  This is the
version that the fix pertains to.  This fix DOES NOT remove the copy 
protection, it only stops the displaying of the copyright notice and stops
the entry of any key.  Here are the steps involved:

	1. REN 123.EXE 123.XXX
	2. DEBUG 123.XXX
	3. U 4F2
	   It should say CALL 0456.  If not, do not continue, wrong version.
	4. E 4F2 90 90 90
	5. W
	6. Q
	7. REN 123.XXX 123.EXE

I have mine fixed up and that is the way I will use it from now on.
