  • Unix like OS in 6502 assembly? Dang. I'm impressed. That's seriously cool.

    • But theoretically not that difficult? I mean, the whole point of Unix was that it is written in C and therefore platform-independent. Principally, all you need to port a POSIX Unix OS is a C compiler for the architecture that you're targeting.

      • I suppose a cross compiler for 6502. What I'm not sure of is what kind of timer interrupts the 6502 supports.

  • Apparently LUnix was originally designed for the Commodore 64 and Commodore 128. I didn't know such a thing existed for 6502-based systems.

    Sounds like it's time for me to raid the closet. The Commodore 128 is a strange beast (considering the Z80 coprocessor that effectively does nothing, unless you boot CP/M) but playing with a tiny Unix-like OS on it seems like a fun project.
