Atari TIA schematics

Atari Age hosts two sets of copies of the schematics for the Atari VCS TIA (Television Interface Adapter), the custom chip that was used in the VCS/2600 for graphics and sound. One set has sheets at 2048 x 1396 resolution, the other is in a whopping 14400 x 9820 format.

Might be neat to simulate the TIA and other VCS hardware in Minecraft and run a ROM entirely in that world. Why not? Something similar was done w/ the Commandore 32!

Another interesting link – a recent rundown of the TIA hardware.

30th anniversary interview with Galaga creator/designer Shigeru Yokoyama

Neat background info on everything Galaga, from the programming to the cabinet design:

“The Core”: resurrecting Atari 2600 homebrew abandonware/vaporware…

…from a single screenshot more than 20 years after it disappeared due to unfortunate circumstances.

Interesting thread here at AtariAge discussing the current effort and a contemporaneous description of the game by the original developer, Paul Oswood, here.

I’d be remiss if I didn’t link to the original screenshot of course:

Digitpress interviews David Rolfe…

…developer of – among other things – the Intellivision Exec OS and Star Fire, the first arcade game to use a sit-down cockpit, and more notably, allow a user to enter their initials after achieving a high score:

Rare and valuable Atari 2600 games

Amazing the obscurity of some of these titles and the resultant sales prices:

Programming the Atari 2600 VCS

As I wrote previously, I’m considering taking a stab at programming Atari 2600 games for fun and _.  May just update helpful links here:

Twin Galaxies records

One of my 2023 goals is to rank on the Twin Galaxies records boards. I’m likely going to have to do it in what I call the “Tim Ferris way” though – by technicality haha…

Then again, there are a lot of really high scores already, at least for the games I currently own. Maybe I’ll just have to shoot for next-to-last rank for Gopher on the Atari 2600.

Interesting read on the technical aspects…

…of the Galaga no-fire cheat:
