I’ll never forget the book. […] The book was a huge compilation of all around interesting stuff. Weird Apple II tricks that were pointless, but endlessly fascinating. Like the fact that there were extra offscreen pixels of lo-res graphics memory that you could write to, that never got displayed. Or how to put “impossible” inverted or flashing characters into your disk directory listing. Or how to modify system error messages.

Once the basic stuff was working, I wanted to load TAP files directly, simulating cassette loading. This was the first time the agent missed a few things, specifically about the timing the Spectrum loading routines expected, and here we are in the territory where LLMs start to perform less efficiently: they can’t easily run the SDL emulator and see the border changing as data is received and so forth. I asked Claude Code to do a refactoring so that zx_tick() could be called directly and was not part of zx_frame(), and to make zx_frame() a trivial wrapper. This way it was much simpler to sync EAR with what it expected, without callbacks or the wrong abstractions that it had implemented. After such change, a few minutes later the emulator could load a TAP file emulating the cassette without problems.
