"Y Ddraig Fach" which means the little dragon in Welsh. I'm continuing the computer naming scheme I started with Y Ddraig. This is my take on what would have been a powerful 80's computer. The PCB has designed with the goal of creating a case for it. The shape of the PCB and the use of a C64 keyboard should allow a case to be designed that will resemble an 80's computer when finished.
