Once I again I stupidly sent my original post straight to the original
poster via my 'reply' button, but essentially I want to ask :

a) "mostly accurate for the Beeb also" - are any instructions timed
differently, or does that just mean all that muttering about zero page
registers and such like, and

b) does anyone know the timing for IRQ and NMI? "like BRK" isn't really very
helpful . . . .
