RE: A86:Multitasking
That wouldn't work for a lot more than programs with their own interrupt
handlers... that wouldn't work for anything that uses temporary space...
Unless you save a copy of page 1, the text shadows, graph screen, the ENTIRE
_asm_exec_ram (in case they use it for temporary data) and who knows what
else for each program (probably you would need to save ~27kb for each
program you are trying to multitask...)

you could install an im 1 or alt_int interrupt that would switch tasks,
but you'd need a separate stack & asm_exec_ram for each program running.
alos, that wouldn't work for programs that inatalled their own interrupt
handlers, such as grayscale routines.
