Lotus 1-2-3 Release 1A

This version of 1-2-3 is known as Release 1A, which differs from the later Release 1A*. This version contained files dated 6-07-83, whereas Release 1A* contained files dated 7-01-83.

WARNING: These disk images are not originals. We've tried to recreate the System Disk as it was originally distributed (aside from the Copy-Protection Patch), but the other disks have been left as we found them: original Lotus 1-2-3 files dated 6-07-83 along with a random mixture of PC-DOS 1.10 and PC-DOS 2.10 binaries (eg, COMMAND.COM, DISKCOPY.COM, DISKCOMP.COM, etc.)

Copy-Protection Patch

The PCjs Release 1A System disk does not include any copy-protection. Instead, the disk contains a patched copy of 123.EXE which bypasses the usual copy-protection tests. The patch is described in the "unprotection" document LOTUS.TXT:

1. Rename 123.EXE 123.XYZ
2. DEBUG 123.XYZ
3. type  U ABA9
4. you should see    INT 13   at that address
5. type  E ABA9 90 90
6. type  W
7. type  Q
8. Rename 123.XYZ 123.EXE

The following hexdump diff confirms the precise differences between the original 123.EXE and the patched copy:
