68000 Editor, Assembler & Simulator

Version 5.1

Write, assemble and simulate assembly language programs for the Motorola 68000 processor in Windows. Includes a list-file viewer, a Dynamic Data Reference tool for tracking register contents, and file associations for .x68, .bin, .lis and .ddr files.

These programs were written for Windows 95–2000 and are no longer maintained. They’re kept here, free, for anyone who still finds them useful. Newer versions of Windows may need compatibility mode.

On Windows 2000/ME and later, install to the root of a drive (for example C:\68000) and apply the Windows 2000 patch.

Registration is free. Run the registration program after installing.
