Of course, changing the IRQ enable may immediately change the IRQ line. Signal if so.

Interrupt enabling works the other way around I think, and both registers with only one bit defined should probably return '1' in all other places?

Gave the Microdisc a clock signal, added just enough of force interrupt to avoid a spurious belief that a type 3 command has started.

Any Oric-format disks that are inserted now make it all the way to the Oric, along with a request to emulate the Microdisc. It has received a copy of the ROM. The ball is entirely in its court now.
