You are absolutely right. I was using old notes and it was late at 
night when I posted this. That's why I didn't catch this error.

Hehe, I did a very simillar thing using my PC in the first version of my
program transferring files between Apple and PC through joystick port.
My keyboard could even retype last line with a single keystroke :)


I wonder if you (or anyone) know how keyboard knows when to send next 
keystroke. For my clone I used to have a keyboard with its own CPU (6800)
and it seemed to know when Apple was busy, say, reading a floppy. It would
then store keystrokes in buffer and send them later. Is this possible or
was it too long ago and I just don't remember?
