Mega 2560 - unchanged. Selected under Tools.Board.
Version 2 arrived when I downloaded the Arduino IDE to the newer laptop and I straight away got the same problem, so I searcehd for an older IDE and selected the oldest before ver 2.
Please excuse my lack of skill & memory! This code was written years ago.
Full sketch and full error message below.

interrupt: the number of the interrupt (int)
pin: the pin number (Arduino Due, Zero, MKR1000 only)
ISR: the ISR to call when the interrupt occurs; this function must take no parameters and return
nothing. This function is sometimes referred to as an interrupt service routine.
mode: defines when the interrupt should be triggered. Four constants are predefined as valid values:
LOW to trigger the interrupt whenever the pin is low,
CHANGE to trigger the interrupt whenever the pin changes value
RISING to trigger when the pin goes from low to high,
FALLING for when the pin goes from high to low.
