A strange thing happened that I can't explain or reproduce.
I was using my UNIX-PC
in vi and noticed that the 'bells' that sound when you hit the escape
key sounded very different. Almost like a buzzer instead of the beep
you normally hear. So I got out of vi and did some other things that
would make the bell sound and it still sounded strange. I can't recall
exactly what I did but the strange sound went away and it returned to
normal.

All this made my wonder if they speaker in the UNIX-PC was capable of
making other sounds other than the beep. I recall being shown how the
Burroughs B20 was able to play music and produce synth speech without
the aid of a chip to do so. I recall it had something to do with the
forming of a wave pattern in 8086 and it would produce any sound you
wanted, so I was told.

My question is can this be done on the UNIX-PC? If so how and has
anyone done it or have an example they could send me.

Thanks in advance.
