Mandelbrot-FPP

This is the classic Mandelbrot set fractal. The program is pretty much self-documenting, its claim to fame is the use of the ZX81’s calculator language directly, to give about a 3x speed increase over straight BASIC. However, it’s still pretty slow… be forewarned. MAND4-FP.P is a quadric Mandelbrot in medium-res dithered greyscale (needs 32K)
