There are quite a number of refreshing things about the Atari 2600 Technical Wiki. There’s its subtitle, “Woodgrain Wizardry,” which is excellent. Its dedication to a 47-year-old game console. There’s it being a wiki that isn’t being hosted on damnable ubiquitous Fandom. Its direct writing style, which gets right to the point of each page. It’s also not a Youtube video, which is sort of okay if you have a Premium account or a working adblocker, but a hellscape if you don’t. Its the kind of page Google Search de-prioritizes if you’re not doing a web-only search, and even if you do that, sometimes gets skipped over.
It is true, this one’s for hardcore geeks and programmers only. I love reading about stuff like how to do large 48-pixel graphic displays, useful for score readouts or title screens, even if I probably won’t ever use that information myself. Or on Bank Switching, which reveals that, since there’s nothing in the system’s tiny cartridges’ ROM space that indicates which bank switching scheme is being used, emulators scan through the executable image looking for signature bytes to determine when to map parts of it to the processor’s address space, and homebrew games try to give them appropriate hints so they’ll work smoothly.
There’s a page, Introduction to Processor Hardware, that gives us the surprising information that some EPROM chips, when used with the 2600, may act unpredictably when used in a dark room. That quality esoterica right there.
