| &F8E8(Write only)
| INTERUPT SEL
| Writing 01 to this port disables internal Amstrad interrupts and replaces the IRQ signal from ACIA. Writing 00 restores normality. ''(Unclear how this works exactly - the description sounds as if uses an [[External Interrupt]] (rather than a [[NMI]]), and as if it does somehow disable the CPC#'s internal 300Hz interrupt?)''
