Made an attempt at getting some interrupts all up inside this thing.

Fixed: turned out the power-on bit was being cleared.

I'm not really sure what's going wrong with paging yet but this fixes the 0xc000 byte error.

Hard-coded to 40 columns of black and white, here's some text, at least.

This now correctly (I think) decodes information posted to the CRT. But doesn't yet post it correctly. I'm very close now, I hope.

Output, at last! Though sync is clearly way off.

Made an attempt to get RGB output mode up and running, and showing at least a box where pixels would be.

Fixed to ensure that frame rendering wraps around, and to properly connect the Electron to its view. Now I need a working pixel shader.

This is intended to be enough to start producing something of an output. But something's obviously still broken.

This at least now connects up a CRT, though it never talks to it.

Added just enough that this is probably a successful boot. I guess I'm going to need to get invested in graphics next? Hmmm.

This is the bare minimum to prove that the ROM is trying properly to boot.

Added the option for the CSCathodeRayView to show only a subsection of the full scan area. Zoomed in a little on the 2600. Put in enough piping to give the Electron sight of its ROMs at least.

You now get an Electron only if you ask for a new file. That'll do for now while it's the only thing that one might want to start without supplying a file. The 6502 now starts from a defined point — being reset. The Electron is starting to grow the absolute most simple buds of its memory map.

Started working on a shell for the Electron emulation, including factoring out the common CRT delegate -> Objective-C bridging, serial dispatch queue and frameskipping logic from the Atari 2600 shell.
