Do you mean pre-emptive multitasking?  This wouldn't even work on the 89
because the processor is just to slow.  In any case, PC's only execute
startSound and endSound instructions -- the sound card executes the rest.
That way the speaker can keep going for that 1/100th of a second while the
WAV player doesn't have control of the processor.  Some ambitious person
could build a sound card for the 89, plug it into the link port and plug
the speaker/headphone into the card thing.  Pipe dream...
