A modern 3D printer being controlled by an ancient KayPro II. It's printing a G-Code file saved on the floppy disk!
@SamTornado and I did an incredible amount of work to get this going. It's connected to the printer via the serial. We also had to figure out how to connect the KayPro to a PC to copy the G-Code over.
Also wrote a custom program in Z80 assembly to stream the file to the printer.
All this to prove that we could have had home 3D printers in the 80s!
