Programming the Super Serial Card (SSC).
http://www.wright.edu/~john.matthews/ssc.html
This is an article I wrote some years ago about how to program
the SSC's 6551 ACIA. It describes a simple terminal program
written in Kyan Pascal and assembly language. It shows how to
install an interrupt routine in ProDOS to buffer incoming data,
bypassing the card's firmware.
The code might prove useful to anyone wanting to use the SSC in
a novel way. For several years, I used the program to configure
and test headless systems.
I'd welcome any comments. (Sorry about the anti-spam scramble:-)
