An MPW emulator! That’s very cool. What I really miss is the MPW environment though. Sometimes I daydream about doing some kind of dyld hack or FUSE filesystem to make MPW-style tool/editor integration work on MacOS/Linux. IIRC, the current iOS app rules don’t prohibit emulation, just downloadable code. There are games running Lua scripts inside, right? Or am I confused? (That happens.) But that does make the ROM a conundrum. I can’t think of any theoretical reason you can’t make a new native version of Newton OS that runs old apps — it’s more or less like making a new browser that runs websites. Of course, you’d need to reimplement some fairly hard things in the undocumented native part of the toolkit, like handwriting recognition. One nice thing about working on the ARM4 to ARM6 was how clean the assembly code is. We didn’t have a source-level debugger, so I spent many many hours debugging C code in an assembly view, and it really wasn’t too bad.
