P/DA2Disk

This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.

Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

   10REM Semi-automatic Disassembler with Disk Output
   20REM (c) Mark Bellis 1997, 1998
   30:
   40REM Most 8-bit Acorn programmers who have a use for this program will know
   50REM many of the opcodes already, and will have a good idea from a *DUMP
   60REM listing whether something is code or data.  This program merely speeds
   70REM up disassembly of machine code programs by a factor of about 20.
   80:
   90REM V1.0 Sep 1997. *DUMP is just not sufficient!  I want to eliminate
  100REM                the hours of disassembly by hand to decode routines
  110REM                in games etc...  Voila! One disassembler!
  120REM V1.1 Dec 1997. Nifty input routine added to eliminate some errors.
  130REM V1.2 Dec 1997. Mode change added for Elk compatibility.
  140REM V1.3 Mar 1998. EXEC output added to enable code reconstruction.
  150REM                (high speed reverse-engineering or what?!)
  160:
  170REM Possible Improvements:
  180REM 1. Add BBR and BBS instructions for Rockwell R65C02 in Master Turbo
  190REM    and 6502 Second Processors.
  200REM 2. Add option to relocate absolute addresses in EXEC mode.
  210REM    This would involve writing decoding functions for all five types
  220REM    of 3-byte instructions, but would not be difficult.
  230:
  240REM N.B. The author takes no responsibility for how this program is used.
  250REM      It is up to the user to use it responsibly and not steal or
  260REM      illegally reverse-engineer code for commercial gain.
