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.

Per the ROM disassembly, the Vic's VIA outputs are inverted for the benefit of the serial bus.

The inversion of truth was clearly just a problematic API. Got explicit. LineLevel might need to become more pervasive.

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

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

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.
