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. -tih -- Most people who graduate with CS degrees don't understand the significance of Lisp.
