Hit and hope is getting me nowhere. Time to unit test this thing.

Messier and messier, but I've at least attempted to implement hardware attention acknowledge.

Still fumbling in the margins: made an effort not to imply that the 1540 is forever reading syncs.

Okay, so the 1540 doesn't toggle the actual attention line. I don't know what it does yet but this helps.

Since the ROM is well disassembled, let's actually try to be a 1541 first.

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

Threw in the second VIA as a currently clearly incorrect thing.

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

Further fleshing out: added a serial port for the serial bus.

Ensured the 1540 ROM gets installed, at least.

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

Created a namespace for Commodore and an empty container file for the 1540[/1] implementation.
