Some major hackiness gives the first line of expected text repeating endlessly (as the end of columns is never reached, as that's back to thinking it's 0x7f); I also don't yet know which actor is supposed to do the '+0x8000' (which probably shouldn't be that but might be a pin on the 6560 indicating what sort of value is being fetched, that effects chip select for the various bits of memory?)

Advanced to having some characters displayed, even though they're obviously very much incorrect and the display is still rolling.

Without yet figuring out what vertical sync is meant to do, moved just about far enough forwards to see _something_ that hopefully I can soon discern characters within.

Made some elementary attempt to hit something like the correct states within the VIC.

Added guess on how colour memory and the 12-bit bus possibly works.

Added enough to the machine that the 6560 can now produce output if it wishes.

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