Re: A83: Re: crack team for LOZ:TOC
You can't do interrupt driven sound on the calculator. The interrupt occurs
at ~200 times a second (usually less). But you need two events, one to turn
it on, and one to turn it off. That means at most you are going to get
sounds with the frequency of 100hz, which is way too low to hear.
