A86: 200 Interupts/Second
There has been going around on the lists the idea that the calc
checks interupts and runs the handlers every 200th of a second. This
sounds wrong to me; I thought that the whole idea of an interupt was that
it didn't need to be checked periodicly because the interupt processing
hardware would get the processors attention when nessecary. I know that
that's how the PC works and the 8xs can't be much different with a Z80
inside.
I heard stories about secrateries outrunning Apple IIs because
the 6502 doesn't have interupt capabilities and must constantly poll (the
keyboard) for input. Pat help us, we need someone to clear up the
confusion. Who's right?
