Lotus 1-2-3 Release 1A
----------------------
This version of 1-2-3 is known as **1A**, which differs from the later [1A* Release](/disks/pcx86/apps/lotus/123/1as/).
This version contained files dated `6-07-83`, whereas the **1A*** Release contained files dated `7-01-83`.
The PCjs **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. Details regarding the [patch](#patch-details) are provided below.

`DISKCOMP.COM`, etc.)
