I’ve spent more time in pdf than ps, but they’re close.

Digging into these details is closer to digital archeology than anything else.

The glyphs inside Type3 fonts are themselves PS programs, right? Theres so much interesting history hidden inside the structure (and in some cases you find weird little edges in the codebases that define the behaviour in a way where that’s likely the only place it lives). There’s decades of legacy in how to draw things with computers.

Glad I’m not the only one who still thinks it’s fascinating enough to spend time understanding!

Probably easier to "just" emulate the LaserWriter. The firmware for some of the models is available, the 68K/68020 emulator can be downloaded from somewhere, and the rest is actually documented well enough for some models that writing an emulator is a very realistic prospect.
