I wouldn't even put test routines (as this was) down at 0000h.
Spurious interrupts could be a real PITA to track down. I
*always* put a handler for each interrupt, even it it is only a
jump to 0000h or a spin loop. I pretty much use one template for
main line programs (pretty much just the POR and interrupt
vectors). Unless I list macros/extrns/constants my "main
program" is rarely more than a few pages, and much of that is
boilerplate/documentation. When I want to test something I just
gleep a copy of a working "main program" and modify it. This
keeps me from making the same misteaks every week. ;-)

It's not the "electronics crap" that bores me. I wish I got to
do more of it these days. Oh well, my mortgage company likes what
I do. ;-)
