Robsonde,

It’s a simple computer, 32k of RAM and only 1Mhz. But it can create a fractal fern.

@Robsonde neat. Where’s the video output? Or does it save to that SD card at the bottom? Would it also work with original MOS 6502 and 6522, or only the modern 65C variants?

Robsonde,

@root42 it just creates a .BMP file in RAM and the. Writes it to the SDcard. ROM supports FAT32.

I am 95% sure it will work with original 6502, but I use WDC65c02

@Robsonde cool. I have a few dead 1541s where I could use the 6502 and 6522 to build this from.

Robsonde,

@root42 it’s about $100 USD in parts, and a lot of that is the key switch’s.

I don’t have build documentation finished yet.
