you might think "if it suddenly interrupts my code won't it fuck everything up?" and/or how do i do anything in that routine. -- generally in machine code you have a 'stack' which is a sort of "most important first" list of stuff to do

but it's all in german, so.

Rapture (10:50:49)
then redraws the chatset on the fly.. ITS SO SCARY but so satisfying to watch. magic wizardry.

Rapture (10:50:33)
there is this one german basic program, that is kind of scary to me. all these pokes. what it does is making the blocky c64 cursor transform into the _ MSDOS cursor. with pokes it copies the 4 charsets from ROM into RAM, then points basic to the new one, t

anyway definitely my first experience of those was how to do background music

mirrorbird (10:50:09)
the important point is that your main code doesn't have to say "now do this" somewhere, the machine will actually interrupt it (HENCE THE NAME) and cut it off

Rapture (10:49:33)
ah yeah

mirrorbird (10:48:45)
but end of the day an interrupt is just a sort of uhhmmmmm imagine if you could write "10 times a second, do a GOTO to this routine, to play a bit more of my SID tune in the background" this is the kind of purpose of an interrupt

mirrorbird (10:48:06)
yeah interrupts are a way to do something like it. at hardware level.

Rapture (10:47:57)
well it's more "software, wait! i wanna see if a hardware thing was used by a user". huuh. I'm no coder
