From Chicago BBS slightly modified.
The new version (1A) of Lotus has a different copy protection
scheme than version 1. To unprotect the new version, follow the
procedure below:
1. Rename 123.EXE 123.XYZ
2. DEBUG 123.XYZ
3. type in U ABA9
4. INT 13 will be displayed at this address
5. type E ABA9 90 90
6. type W
7. type Q
8. Rename 123.XYZ 123.EXE
That's it. You can now copy 123.EXE over to a hard disk using PC-DOS
copy function and not require the Lotus System Disk in Drive A.
