Years ago I ran into something on an Apple II FTP site that claimed multi-
tasking. It required an Apple II Mouse card to provide the interrupts for
task switching. I do not recall what limitations it may have had.

I _think_ it was a Prodos 8 shell, but I am not certain.
I _think_ it was on the Michigan Apple II FTP site.

About the same time I ran into a set of Apple II assember code utilities to
do multi-tasking via well behaved tasks that relinquished control to a
round-robin style scheduler after executing some small portion of code. By
today's standards it might be more appropriate to call this one multi-
threading?
