WARNING: These disk images are from WinWorld and are not exact
copies of the original distribution disks. 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.)

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 “unprotect” 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:
