interrupt handlers. I was lookin over my z80 book and i realized it would
be 300 bytes, which is kind of a lot, but its a lot better use of those
300 bytes than an option screen or a password feature. This way, when
someone goes into the graph screen, the calc doesnt crash.
Does anyone have a table of the addresses all the rom-calls used in
zshell programs for all the roms, but more importantly rom 10? Im
thinking about taking a shot at writing a shell. (No recompilation of
programs needed)
