Other key parts include the W65C816SxP, 74HC74 and NE555P. By type, the board carries 11 capacitors, 4 ICs, 2 switches, 2 resistors, 1 crystal and 1 connector.

It belongs with the dev boards & breakouts and displays & leds designs in this gallery.

From the project

My Personal 65C816 breadboard build, including schematics, etc.

/KiCad contains my schematics/raw kicad files, if you want to laugh at my design.

/Software contains the programs I've written, mostly raw assembly, but I will hopefully have a C compiler up and running eventually.

/Docs will have a variety of documents on the exact nature of each hardware decision and how it works. I'll also be publishing these to a blog on my web zone.
