I am looking for a solution that has plagued the Apple II for as long as I can
remember.

Right now I am working on several projects where it is going to be necessary
to perform disk writes while data is still coming into the serial port.

From my experience with II's over the last six years, I don't believe I have
ever seen this done without character loss.

For the two things I am working on, it is imperative that I not loose
characters when the writes are performed.

If anyone has any suggestions on how this could be performed (either through
software AND/OR hardware) PLEASE give me ANY ideas the come to mind.

(By the way, what ever happened to the "hacking" spirit of the Apple
II where nothing was impossible if you just put your mind to it.  I still
remember when I would go over to people's houses and see their ][ and ][+'s
with enough wires and modifictions in them to re-wire a major metropolitan
area??  That's what truly made the II a strong computer.  People believed in
it and were proud to say "I have a II!")

Just thought I would mention the above.  Its something I have been thinking
about a lot lately.  I have been looking back at how I saw the II years ago
and how I see it now.  It sure has changed....

ANYWAY, if anyone can help me with my interrupt/serial port problem, I would
appreciate it.


Thanks!!
