It is based on an algorithm published on pouet in 2021. Its implementation uses 16 colors. Generated pictures are 128x256 raster images. It is very likely that this algoritm implementation is the fastest known Mandelbrot set computation routine for the 8088/8086.
An archive-file with COM-executables is here. As an extra it contains a fullscreen EGA (640x350 16 colors) Mandelbrot generator v4 which can draw, for instance the next image.
