; Draw a mandelbrot in graphics mode (the image will be 256 x 200 pixels).
; NOTE: this will take an eternity to draw on a real c64. A CommanderX16 is a bit faster.
; even in Vice in warp mode (700% speed on my machine) it's slow, but you can see progress

; Note: this program is compatible with C64 and CX16.
