Virtual Machine of the HARM8, my 8-bit CPU

This is a virtual machine of the HARM8, which is an 8-bit CPU I designed. It reads binary as the program from prgrm.txt. An assembler for more easily programming it is available at This is also part of a repo on Github, at

Any plans for a simple operating system that could run something like BASIC?

@jort57 I'm thinking of a TUI (Terminal User Interface) that can directly access information from the CPU, with maybe a simple text terminal app as well.

Lol I know im late but just as a general question, lets say I made it run an operating system would that work

It's not running. Getting:

Traceback (most recent call last):
  File "python", line 162, in <module>
  File "python", line 110, in loadPrgrm
ValueError: Program passed to loadPrgrm had an incorrect word size

@amasad That's because prgrm.txt is empty. Fork it and add a binary program to prgrm.txt for it to run.


@HappyFakeboulde so how we do that :(
