Discovered that the VIC and the VIAs can be simultaneously selected. Adjusted bus appropriately.

Implemented full paste ability for any machine that is a typer.

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.

Established a general pattern for machines that can type things. Started working on the Vic typing itself.

Switched to clocking the 6522 by the half-cycle. Very trivial test now passes.

Fixed tone channels; made an attempt at loading PRGs that are supposed to go into RAM.

No need for these to live separately, I think.

Added just enough hopefully to allow implementation of the keyboard-input VIA.

Attempted a square wave, made the Vic itself responsible for address manipulation re:the 6560.

Attempted switching back to a square wave for the composite video and otherwise implementing what's necessary to get to that flashing cursor — the 6560 returns its scan line and the timing bits of the 6522 are appearing.

Increased logging slightly, ensured all of colour RAM can be read, slightly improved the 2600 pixel decoder.

Decided to turn the 6522 into a template, since it's a per-cycle thing with variable behaviour. Added appropriate memory map callouts to hit the two in the Vic. Though they don't yet do anything.

Switched to a real (unexpanded) memory map, meaning that nonsense is no longer being supplied to the VIC.

The Vic now captures the ROMs sent to it and has just enough infrastructure to get to a black screen. Progress!

Kicking the ball a little further down the road, ROMs and PRGs now reach the actual emulated machine.

A CRT is still absent but this moves the ball back into the C++ side's court.
