Hi Marko! :-)

Yep, I know that one (I used it back then) but later found out that I'm 
just better off with one interrupt plus a "delay line" code, whose delay 
is function of a timer (or the $ff1e register of the Plus/4 ;-) ). This 
method simply costs few cycles... and is also less tricky.


Best regards!,
