Your periodic reminder that you can (and should) visit @soffronoff's "Apple Boot Theater" page. It now includes Total Replay in screensaver mode alongside a never-ending stream of random Apple II boot videos. Feel free to leave it running at the Apple store or any publicly accessible kiosk.
I wrote a "chaos monkey" script in MAME's Lua scripting engine that semi-randomly presses keystrokes to exercise every path in Copy II Reboot, and it helped me eventually nail down a combination of actions that can put a Superdrive in a permanently-busy broken state where the drive ROM freaks out and fast-fails every time you call it and manipulates the stack in a way that crashes the caller. So that's fun. (The bug also exists in Copy II Plus v8.4.)
Meta-note: this is the GOOD STUFF. This took me HOURS to debug, and in those hours I developed a mental model of a complex operation AND learned something new about ProDOS internals AND tested and discarded several theories before finally discovering the root cause and it was ALL WORTH IT. I don't want to outsource that to Dr. Flattery the Always-Wrong Chat Box. Why would I want to skip this? This is the WHOLE THING.
As I mentioned last year, I acquired the source code to Copy ][ Plus v8.4 at @init_hello 2025 and proceeded to refactor the hell out of it, fix some 40-year-old bugs, and add some small quality-of-life updates. INIT HELLO is happening again this year <https://init-hello.org/2026/01/init-hello-v2-coming-this-summer/>, and I plan to release this project and (if accepted) give a presentation about it.
One of these will push you into an oubliette of self-hatred and self-harm from which few people ever financially or emotionally recover, and the other is heroin.
