Neander Machine with Extended Instruction Set.
This is a simple computer simulator. There are a few simulator out there, but they are usually desktop programs, we need to download it, install it, and... usually it only runs in Windows environment. To be able to call procedures it needs to have stack and some extra instructions. Also I added some devices, which can be accessed by memory mapping. The simulator is able to be interrupted, I planned to add some input devices to use that functionality. Have fun.
