> Isn't the CPU in the 2600 a M6507? A Cut-down version of the 6502 with no > interrupts? Yes. However the PIA can be polled to find if either interrupt had occured. Like I said, this does no good to determine if the timer overflowed, (as you can simply poll the count) however, you can use the feature as edge detection. > Incidentally, a new bug fix version of PCAE (v2.3a) is out.
