I too wrote a TIS-100 simulator in C ( https://github.com/hthh/tis100sim https://github.com/hthh/tis100sim ) - it's interesting to compare styles. (I get a bunch of errors on OS X unless I change "CC=gcc" to "CC=clang", btw)

That gcc error is strange, since I think in the recent versions of OS X gcc is just an aliases for clang. Here's my output of `gcc --version` on OS X 10.10: Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1 Apple LLVM version 6.1.0 (clang-602.0.53) (based on LLVM 3.6.0svn) Target: x86_64-apple-darwin14.3.0 Thread model: posix edit: also, should've said that's really cool and thanks for posting your source code.

  My GCC seems to be GCC (don't remember why - I guess I installed it for something). I can also make it build using "--std=c99" (but that makes the undefined behavior mentioned in issue #2 show up, which is why I went with clang). gcc: warning: couldn't understand kern.osversion '14.3.0 gcc (GCC) 4.8.2 Copyright (C) 2013 Free Software Foundation, Inc.

Well, I wrote one in Haskell, so there! (Currently trapped in legal hell. I work for one of those annoying companies that claims ownership of everything I do, even in my personal time, so I have to get it cleared before I can push it to github...) I added some extensions to allow one node to program another; the PROGRAM <dir> opcode resets the node in that direction, and it can then be fed a series of numbers which form the program. Once complete it starts executing. With this, it ought to be possible to program an arbitrary network with programs from a boot ROM attached to a single node at the corner. It would have to propagate the distribution program through the network, which would then in turn propagate the program to the right place and reprogram each node in turn. Because a programmed node wouldn't contain the distribution program any more we'd have to start at the outer edge and work inwards. I do wonder whether it would be possible to get real work done with this. I bet a node could be implemented in a tiny handful of FPGA gates.

  There's a reason to move to Silicon Valley - its illegal in CA for a company to claim work you do on your own time.
  - mondoshawan 11y ago
    This is not quite correct. Even out here in CA you still need permission if your employer has an invention assignment agreement.
    - JoeAltmaier 11y ago
      They ask you to sign those, but the state doesn't permit them to claim inventions done on your time on your equipment. Don't be fooled.

        You will still want to work with the company so there is proof that you both agree you are exempt.
        JoeAltmaier 11y ago
        You can't sign your rights away. The company document is void.
        lfowles 11y ago
        I'm not arguing that. Completely disregarding the void document, you will still want to document _and notify_ the company that your IP is in the exempt category. I'm assuming the law is similar to Kansas Statute 44-130[0] (d) Even though the employee meets the burden of proving the conditions specified in this section, the employee shall disclose, at the time of employment or thereafter, all inventions being developed by the employee, for the purpose of determining employer and employee rights in an invention.

I just learned about your project today and it's fantastic! We must think alike.
