What is Sim68 for Mac?

This application is a simulator of the 6811, an 8-bit microcontroller by Motorola, and has been ported from a MS-DOS version by Ted Dunning.
  
The core of the simulator remained almost the same (and with small effort it would be possible to extend it to other 68xx-family microprocessors) while the interface became a strange mixture of UNIX and Mac style (sscanf mixed with FSRead and similar).
  
The back-bone of Mac-specific code is David Eck's MacStarter, an application shell which has been extended to implement a primitive multi-window text-editor with file support.
  
In Sys7 it is now possible to drag & drop text files; files with a S19 or HEX suffix are loaded as code, while others are opened as text (the same as if you double-click). And, if it can be of some use, the simulator runs also in background.
