Lotus 1-2-3 Release 1A*
This version of 1-2-3 is known as Release 1A*, which differs from the original
Release 1A. This version contained files dated 7-01-83,
whereas Release 1A contained files dated 6-07-83.
Unlike the Release 1A disks, these disk images are from the private PCjs disk collection, and aside from the Copy-Protection Patch, we believe they are authentic copies of the original distribution disks.

Copy-Protection Patch
The PCjs Release 1A* System disk does not include any copy-protection features. Instead, the disk contains a
patched copy of 123.EXE which bypasses the usual copy-protection tests. The patch is described in the “unprotect”
document LOTUS.TXT:
There is another version of Lotus 123 also called Release 1A
but with a different copy-protection technique. It can be
identified by an "*" that displays on the first screen under
the "s" in the word "Release"
Release 1A
*
To unprotect this version so it can be run on a hard disk
without requiring the SYSTEM DISK in drive A, do the following:
1. RENAME 123.EXE 123.XYZ
2. DEBUG 123.XYZ
3. Type U AB8C press ENTER
You should see MOV CX,0002
if you don't, something is different and this won't work.
4. Type E AB8C C3 press ENTER
5. Type W
6. Type Q
7. RENAME 123.XYZ 123.EXE
That's it. It will now run from any drive. As always, this patch
is provided so that honest people don't have to suffer the
inconvienences imposed upon them by software manufacturers.
When DEBUG is used to examine our 123.EXE:
-U AB8C
08F1:AB8C C3 RET
08F1:AB8D 0200 ADD AL,[BX+SI]
...
This confirms that 1) C3 (RET) has been stored at the specified location, and 2) the remnants of a MOV CX,0002
instruction still reside there.
WARNING: LOTUS apparently released other 1A* 123.EXE binaries, with the same size and date, but with rearranged
contents. This may have been an attempt on their part to defeat a universal patch.
