UNPROTECT BROWN BAG WORD PROCESSOR Version 2.55
The following unprotection scheme is for the diskette that was distributed with
the April 15, 1986, issue of "PC". At the time of this writing, the code is
known to start, but it is unknown if there is a secret gotcha.
Anyway do the following:
1. Insert original into drive A:
2. Insert a formatted diskette into drive A:
3. Enter: COPY A:*.* B:
4. Remove diskette from drive A: and put it away.
5. Enter: B: (Change to drive B:)
6. Enter: REN ED.EXE ED.XXX
7. Enter: DEBUG ED.XXX
8. Enter: U E7BC
9. You should see the following:
xxxx:E7BC CD13 INT 13
xxxx:E7BE 7249 JB E809
xxxx:E7C0 8A87FF01 MOV AL,[BX+01FF]
(more lines follow)
10. If you don't see the above three lines, forget it.
11. Enter: E E7BC EB A1
12. Enter: U E7BC
13. You should now see the following line:
xxxx:E7BC EBA1 JMP E75F
14. Enter: U 2B9D
15. You should see the following lines:
xxxx:2B9D 9A0000470C CALL 0C47:0000
xxxx:2BA2 9AFE8E2C03 CALL 032C:8EFE
xxxx:2BA7 C7061AEF0000 MOV WORD PTR [EF1A],0000
16. If you don't see the above three lines, something is really wrong,
since you got the first change. I would give up again.
17. Enter: E 2B9D EB 03
18. Enter: U 2B9D
19. You should now see the first line changed to:
xxxx:2B9D EB03 JMP 2BA2
xxxx:2B9F 00470C ADD [BX+0C],AL
20. Enter: W
21. Enter: Q
22. Enter: REN ED.XXX ED.EXE
The first code change removes the copy protection checking routine and the
second change removes the number of tries checking. These changes can be
done, even after the three tries has been used up.
That is it. The program is now ready to use. You can install it on the hard
disk by just copying the files from the floppy to the hard disk. Don't use
the programs included.
As a side note, you can not print the manuals using the PR command. You must
print them using something else, as imbedded printer controller commands are
in the file and PR tries to do them, failing.
As another little tidbit of information, you can get more than three tries
if you had made a copy of the original diskette BEFORE using any of your tries.
The file AFILEONE.TXT contains the number of tries. You keep a copy of that
around and when you use it three times, you copy the backup copy to
AFILEONE.TXT and you end up with three more tries. The AFILEONE.TXT is not
needed and can be removed from the hard disk, if you did the above stuff.
