One-Hour Mandelbrot: Creating a Fractal on the Vintage Xerox Alto

Reminds me of writing programs to map the Mandelbrot and Julia sets onto the display of my Kaypro 2X. Didn't even have real bitmapped graphics -- just a way of packing... I think it was 4-pixel squares, into a character representation and then writing that.

Similar to packing up bits to characters shot to some sort of dot matrix printer attached to VAX, to print out such images, a couple of years earlier. At least that generated the images more quickly.

The Kaypro 2X was long in the tooth, by that point.

I wonder whether it will still fire up?

There's a "mode" if you will, on CGA cards, that involves something similar - best explained here:

If this hasn't already been featured on HN, I'd be surprised...
