Author: Carolyn Scheppner, Commodore-Amiga A simple 68000 disassembler. Reads standard Amiga object files and disassembles the code sections. Data sections are dumped in hex. The actual disassember routines are set up to be callable from a user program so instructions in memory can be disassembled dynamically. Author: Bill Rogers, Univ of WAIKATO (New Zealand) Example of a keymap structure for the Dvorak keyboard layout. Untested but included because assembly examples are few and far between.

Author: Bjorn Benson, modifications by Fred Fish Some science demos. Sidereal is a tutorial program which introduces the user to the relationships between Julian and calendar dates and solar and sidereal times.
