A classmate and I discovered this while learning Z-80 machine language
programming on his TRS-80.  Of course our programs hung all the time,
but we discovered that with a cheap transistor radio, not tuned to any
station, sitting next to the TRS-80, we could learn to follow the
execution through the BASIC code, into our machine language subroutines,
and through the various parts of those.  After a while, when our
programs hung, we'd usually know just where it had happened.
