05/07/86 UNPROTECTING SPSS/PC+

***************************************************************************

THIS UNPROTECT IS ONLY KNOWN TO WORK WITH THE VERSION OF SPSS/PC+
RELEASED WITH THE FILE "SPSSPCC.COM (or SPSSPC.COM after
installation) OF SIZE 16100 DATED 8-12-85 TIME 6:51p (as reported
by a DIR command).

WHEN YOU APPLY THESE CHANGES, YOU WILL NO LONGER NEED THE KEY DISKETTE.

***************************************************************************

1. MAKE A COPY OF SPSSPC(C).COM AND PUT AWAY THE ORIGINAL.

USING YOUR COPIED VERSION OF SPSSPC(C).COM:

2. DEBUG SPSSPC(C).COM

3. R --- record the value in the CS register, say XXXX.
Let ZZZZ = the value in the CX register plus 0100 (hex).

4. D CS:1018
You should see the following string of bytes:
C4 5E 1E 26 8A 27 ....
If you do, proceed to step 6, otherwise,

5. S CS:0100 CS:ZZZZ C4 5E 1E 26 8A 27 If debug returns no address
where this byte string is found, you have a different version and
should just type "q" to get out of debug --- this will not work
for you. If debug returns more than 1 address where found, you
could try proceeding with step 5 trying each address
XXXX:YYYY (ONE AT A TIME!!!). Can't promise anything, but who
knows???

6. E XXXX:YYYY (where YYYY is 1018 if you got here from step 4 or
YYYY is the value you got from step 5).

7. WHEN YOU SEE C4., TYPE A 90 AND A .

YOU HAVE NOW UNPROTECTED SPSS/PC+ TO THE POINT WHERE IT NO LONGER
NEEDS THE KEY DISKETTE!!!

NOW, TO GET RID OF THOSE ANNOYING WARNINGS ABOUT DUPLICATION AND
COPYRIGHTS:

8. F XXXX:2E6E XXXX:2E91 20

9. F XXXX:3AC6 XXXX:3AE7 20

10. F XXXX:3AFE XXXX:3B21 20

11. F XXXX:3B41 XXXX:3B54 20

12. F XXXX:3B78 XXXX:3BA2 20

13. F XXXX:3BC3 XXXX:3BD4 20

14. F XXXX:3BE3 XXXX:3C20 20

15. F XXXX:3C41 XXXX:3C54 20

16. W

17. Q

THERE YOU GO...REPLACE THE ORIGINAL VERSION (KEEP THE ORIGINAL IN
A SAFE PLACE!!!!) OF SPSSPC(C).COM WITH YOUR NEWLY DEBUGGED
VERSION AND YOU SHOULD NO LONGER NEED THE KEY DISKETTE TO RUN SPSS/PC+.

HAPPY COMPUTING.

  1. Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

  2. This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

  3. But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
