Does the Kaypro do graphics?

If so, there is a client written in C, I believe.

The kaypro '84 variants can do 160x100 graphics (each character is a 2x4 block of pixels, and the screen is 80x25 characters).

I took advantage of that to generate Mandelbrot and Julia set graphics on one. It was fun as a coding exercise, but pretty slow processing.

And there were add-on boards that gave higher resolution (very relatively speaking) graphics.

Totally understand. At that time 300 pixels horizontally by pretty much anything vertically was considered high resolution.

The cool thing about machines like the Kaypro was the dot clocks were actually pretty fast, so add on boards tended to do fairly high resolution if you got one. Might be 640 by something, or 512...
