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.  manufacturers.
