Title: IRQ $314/$315 and a clock routine..
Post by: stiggity on July 23, 2010, 10:25 AM
I'm Back!!
If im vectoring in a TOD clock,  and i get to the end of my clock routine, i know on the 64 you perform a JSR$EA31 to drop-back to basic..or exit the interrupt, what is the equivalent on the 128??

That would be a JMP $FA65 to execute the std. IRQ
(a JSR would mess up the stack - do not use !!)
