Currently Playing: Three fractals running at once on a 640K IBM XT - see the memory map

Booting a real 4.77 MHz XT off two floppies and launching three Mandelbrot renderers at the same time - then opening the task manager to watch them sit at 6580, 6740 and 6900 in the memory map and keep drawing in the background. Also: preemptive vs cooperative, switched live. Clipped from the full video: os8088 now supports more than 640K.
