Quick fixes properly to declare the DriveVIA, to ensure its interrupts take effect, and to wire ATN IN to CA1 rather than CB2.

It appears that the attention line is also wired to CB2. So the ball is back in the 6522's court.

Made an attempt to allow the 1540 to talk back to the Vic, and to receive interrupts. Also slightly disambiguated debugging logging.

Furthered fleshing out of the 1540. Though it doesn't yet receive a ROM so won't even attempt to do anything meaningful.

Attempted to separate out the concept of a serial port and a serial bus, since the bus may be shared, and to establish half duplex communications from the Vic.

Added a 'power on' flag that is set automatically at construction but can be declined. Saves all that stuff of every machine having to set and then unset the RST line, and fixes an Electron bug related to that.

So it sounds like the user-port VIA might actually be connected to NMI?

Made a first attempt to implement the full top-to-bottom change of clock rates, giving the Atari the ability to change rate when it switches to PAL mode, as it should always have been.

|
Expanded typing to include phase for machines that need to go through multiple keypresses to reach a certain state, expanded Vic to be able to type most things (still bodged on lowercase though), and to schedule a 'run' if it's supposed to be loading into RAM, spotting that opportunity actually to do so.
