In a previous post I talked about the 1802 Assembler I was playing with when I revisited an ancient 1802-based FIG-Forth implementation.
Since it was a pain to get that code running on real hardware, I also threw together an emulator. This was done in Objective-C for the Mac.
Note that the core emulation code is written in ‘C’ however, so it should be quite portable.
It is fairly quick, although I have not tried to quantify it’s equivalent speed.
It will build under recent Xcode versions such as Xcode 6 or Xcode 7.
Listing files can be loaded and executed. There is application-specific code to treat some of the IO ports as serial input/output to a simple terminal facility.
This is in no way a polished final product, but it is made available on the off chance that someone else might find the code useful or interesting.
