Superfast Mandelbrot generator

It is based on an algorithm published on pouet in 2021. One its implementation uses planar writing mode and another color writing mode. Generated pictures are 256x256 raster images (128x256 Mandelbot dots are computated) and show 4 or 8 colors respectively. It is very likely that this algoritm implementation is the fastest known Mandelbrot set computation routine for the 8080.

A zipped disk image with the executables is here. It contains four files:
