Made an attempt to introduce an intermediate buffer that ends up with a bit mask of all graphical components present on it, and to use that to infer collision flags and colours, based on playfield priority and colour palette. Immediately yielding: a blank screen. Good work!

Started trying to be a bit more explicit about usage, and to divide up drawing responsibility.

Added some additional documentation, started making steps towards returning sprites, fixed a counter bug that would exhibit as incorrect sync.

Attempted to retain more player information, and removed the output cursor from class storage as I think it's acceptable as a temporary.

Reinstituted the playfield. Probably needs more buffering though. Time to look into delays.

Made a first attempt at switching to a model that respects blank and sync.

Some mild fixes get me up to having a rolling screen of vertical lines. Which is what I was hoping for right now!

Prevented unbounded CPU usage, albeit without yet deciding who has authority for the clock rate.

Attempted to reintroduce enough logic to handle [most of] line timing, such that WSYNC works. Initial objective is to get back to having a working background.

Supposing the TIA were implemented, this is (more or less) what the Atari 2600 would now look like.

Created a placeholder class for a factored-out TIA. There's a bit more it'll need to do, like vending (or receiving) a CRT but this is the full hardware stuff, I think.
