WOOHOOOO
KnightOS SDK, on Plan9, can now build the kernel, compile userspace binaries, annnnnd write a file system into the ROM and emulate it!
I've got a hello, world in asm being written to the filesystem as /bin/init, and the emulator is dumping the output as braille to the console
(KnightOS is a UNIX-like operating system for TI calculators. I've almost got a fully working build system on 9front, just need to flesh out a few more bits of the SDK
...and then port them back over to Linux so I can kill the garbage we've been using there)
