Here's a tour through some demos and test of my 6502-based system. The demos were intended to showcase its speed, but the flaw in that plan was not really being able to compare that against anything!
Some of the demo code is available on github:
Life - https://github.com/gfoot/life6502
Mandelbrot - https://github.com/gfoot/mandelbrot6502
Prime Sieve - https://github.com/gfoot/primesieve6502
