About the 65c02board PCB
65c02board is an open source PCB design by c0pperdragon, published on GitHub. It is a 2-layer board measuring 22.9 × 83.8 mm, with 6 components from 5 distinct parts.
Other key parts include the W65C02 and 74HC00. By type, the board carries 2 ICs, 2 capacitors, 1 connector and 1 resistor.
It belongs with the retro computing designs in this gallery.
From the project
A generic main board to build 8-bit computers
The 6502 is one of the best known 8-bit processors as various variants of it were used in many 8-bit computers of the 80th. Apple, Commodore, Atari, Acorn and many other manufacturers used this CPUs to drive their products. Genuine old parts may probably be difficult to get, but luckily there is a not-so-modern variant that is still in production: WD65c02.
It is relatively simple to wire up this chip to the ByteMachine. You basically need one additional 74HC00 chip (quad NAND). In my tests, this setup is able to run at 16Mhz without any issue. Even 20Mhz were possible with a bit of extra…
