It uses a m68k CPU emulator and implements a bunch of Classic traps, just enough to run most (all) the Newton tools like they were a regular command line app.
I love the seamless integration of the HWR into the OS. And the ability to draw and write anywhere. Todays devices all go a different path.
Yeah, the C code translates quite well back and forth to the ARM code. I have tried to understand optimized Intel assembler, but failed miserably ;-D
Even the Palm SDK was commercial in the beginning. But a free toolchain was put together by some hacker after a year or so, which subsequently convinced Palm to lower their price and eventually give it away for free IIRC. Then again, even VisualC 6 cost 400$ or so back then.
As a novelty, I like to have Einstein running NewtonOS on my Samsung Note 10 which is now really fast and quite impressive for a machine from the 90's.
Apple has refused Einstein for iOS at least once. They don't allow emulators, especially not Apple product emulators, and they don't like the idea of downloading ROMs. Do you have any suggestion on how we could get EInstein into the app store nevertheless? Or how to get around the ROM issue?
Maybe related, I wish we could bring NewtonScript into the 64bit world, surrounded by an updated NewtonOS. There is already half of the ROM rewritten as newton-framework on GitHub. Do you think it is possible to rewrite the rest? To get a truly native framework going? How would we do that?
Anyway, I wanted to thank you for creating this huge Sudoku puzzle for us. I have a great time tracing your steps and understanding NewtonScript and how it works inside NewtonOS. I have manually disassembled thousands of lines of ROM code, and it's just great fun to see smart code.
