    • create OSX and Windows releases
    • automate builds
  • cpu
    • decide on stack vs register based architecture
    • eval stack and tests
    • nop, push and pop
    • add, sub, div and other arithmetic
    • signed arithmetic
    • jmp, je, jz and similar
    • call and ret
    • interrupts and iret
    • means for talking to hardware (out)
    • sleep mode while waiting for interrupts
    • stack frames and local storage
    • PC and RS relative addressing
