* [BUG-65 Version 2.0 Manual with ERRATA|BUG-65 Version 2.0 manual-final with errorpage.pdf] ; size: 2.7 MB ; this manual contains as the only one an error page: 'ERRORS IN YOUR BUG/65 MANUAL' (page 4 in the pdf file). As of this moment, it is not understood, why the there mentioned commands: N, O, R', R", W' and W" do not work with the above version 2.0 of BUG/65. Either we have version 1.1 for real, while 2.0 is shown at start or something else is wrong here. Anyway, the mentioned pages on the error page do match with pages in the rest of the manual. Maybe the 'old boys club' from the golden age can solve this? Any help in that case is very welcome at any time. We really appreciate if you can help us.

Further, the below mentioned BUG/65 version 4 patch should not be done, according to the error page from December 1983(?), while it should be done according to the OSS newsletter from summer 1983. Maybe just the 'old boys club' from the golden age can solve this? Any help in that case is very welcome at any time. We would really appreciate if you may can help us here. :-)

! BUG/65 patch from OSS Newsletter October 1984:
When BUG gets control as the result of a BRK instruction being executed, it actually checks to see it the BRK instruction is one which it placed (as a result of a "G" command). If not, it assumes that it is a user breakpoint, to be handled by a user routine! Guess what? Most of us don't go around adding user BRK handlers to Atari’s OS, so the machine goes off into never-never-land.\\
\\
Quick hix (again, not hor the faint of heart): After loading BUG/65 from CP, perform the following actions:\\
\\
1. Display the contents of location $2E7 (LOMEM).\\
2. Use the "H" command to add $17EE to those contents. (Example: if $2E7 contains 2200, use "H 2200 17EE” to find the sum.) Call this value ADDSUM.\\
3. Display the memory at ADDSUM (via the "D" command. You should see the following bytes (if not, stop now): 39EE E9 02 4D . . . ("39EE" is arbitrary-value of ADDSUM if LOMEM is at $2200.)\\
4. Use BUG/65 commands as follows:\\
\\
Z 600\\
LDA #B0\\
STA addsum (use actual address instead of name!)\\
LDA #1E\\
STA addsum+1 (again, use an actual address)\\
BRK (hit the BREAK key to exit miniassembler)\\
G 600\\
\\
If you did everything correctly, BUG/65 should allow a "USER RUN" and then print a breakpoint message for the BRK at $60A. If it didn’t work, you may have an already-fixed version of BUG/65, so ignore all this.\\
