Want to borrow: Melzi board for makelangelo firmware

I’m looking for old 8 bit creality boards from ender3s. I hear there are a lot around. The goal is to add support in Makelangelo-firmware, which is open source cnc firmware I maintain. Pull requests with support welcome, board a good second place. If you can help please reply.

Also I just got stm32 support working, so 32 bit controllers are starting to join in.
