Look, my VM computes! I wrote a simple program to first initialize the accumulator to the value 15, then repeatedly increment the accumulator forever.

I don't have an assembler yet, but I *did* write a python script which lets me create a file with the bits I want more easily... With an ISA as simple as mine, that's almost as good as an assembler

I also made my repository public: https://github.com/mortie/scisa

Alright I have designed a little ISA: https://gist.github.com/mortie/d678c4663fe705219e5dfe90e0bbdc3d. It's somewhat 6502-inspiret, but I think it's cute.

Not done yet, but I think it's a decent starting point. Next step: writing a VM and an assembler...
