How interrupts work (x86 vs. C64)
Hi,
Some time ago I used interrupts at Commodore C-64. When I preset address
of system interrupt (as I know there was only one interrupt available)
to my code (which ended with jump to original address of interrupt) the
result was, that my code was repeated continuously (~60 times pre
second, in other 'thread'). The interrupts at x86 seem to work
differently. How do they work, and how to 'emulate' behavior of
interrupt from C64 ?
Many thanks,
MJ
