Ian, I'm sure it's been doing this for the last 34 years or so ;) Encouraged me to rough up a 68K controller for old school kicks though ..Cheers

I've just spent nearly a day and a half trying to debug a simple bit of assembler code because I forgot that on m68k CPUs the MOVE instructions alter the flags and I was convinced all sorts of other problems might've been the cause, but in the end all I had to do was swap two instructions: move.l d5,d0 and.l d6,d0 <- moveq #'0',d1 <- beq.s sk1 moveq #'1',d1 sk1 ... should've been: move.l d5,d0 moveq #'0',d1 <- and.l d6,d0 <- beq.s sk1 moveq #'1',d1 sk1 ... That'll teach me not to try to develop the same program on two different platforms at the same time! Damn damn fume blast ... Never mind though, might be a little something for QL Today when I've tidied it all up.
