I made that text file that is floating around.

Recovered it off of the tape myself.

Basic uses the ACIA ROM to do serial I/O. It also uses the KCACR ROM for tape I/O. You should be able to just write your own ROMs or change the call locations for those ROM calls.

Download the attached files for the two versions of KCACR basic. These files are ready to be transmitted as is to the ACIA monitor ROM in the 680.
