Imposes a three-cycle penalty for SN76489 access.
This is my reading of (i) the SN76489 data sheet; plus (ii) the ColecoVision schematic.

Ensures all audio queues are fully merged before machine destruction.
Thereby avoids a race condition.

Provides the proper framework for encapsulation of analyser target specifics.
... while making them a safe container for objects too. Uses the ZX80/81 as the pilot platform.

Fixes underpumping of SN76489.
Audio works now. Though I still need properly to confirm who owns dividers in practice. I think probably all division should be within the SN.

Also provides symbolic input from the Mac.

Extends JoystickMachine protocol to cover ColecoVision use case.
Also thereby implements input on the ColecoVision, in theory at least. No input is being fed though, so...
