Description

This is a version of Grant Searle's Z80 CP/M machine.

Some changes have been made:

  • Reduce the Serial Communications speed by a factor of 6 (now 9600 or 19200 depending of the crystal frequency).
  • A debounced Warm and Cold Reset.
  • Expansion port

 

I have also uploaded file2hex.run (that runs under Linux) to replace Grant's windows "FilePackage.exe".

It works the same except it is a command line program and only proccesses one file at a time.

Just cut and paste each file into a single text file and no one will know any better.

My program works with CP/M ascii files properly.

See "doit.sh" for an example.
