Zektor uses the stack. What I was observing was the state of the registers
when the display interrupt occurs. Most of the time the processor will be
halted waiting for the next 40Hz interrupt. If it's really idle, i suspect
it resets the stack pointer to keep it from underrunning RAM. It doesn't
ever appear to use much of the stack space (<32 bytes).
