... and that reminds me about the use of a high-speed oscilloscope
to watch your program run (works best on a single-user machine):
Assuming for example 16-bit addressing, put the lowest 8 bits of the
PC on a high-speed DAC, the highest 8 bits on another, and connect the
analog outputs to X and Y channels.  It is amazing how much information
one can glean from watching this display.

Does anyone remember the days when computers had switches and lights?
