Cpu new
About the Cpu new PCB
Cpu new is an open source PCB design by Noah1989, published on GitHub under the MIT license. It is a 2-layer board measuring 160 × 100 mm, with 58 components from 21 distinct parts.
Other key parts include the Z84C0010PEG, LY62256PL-55LLI, 74AC138, 74AC245 and 74AC10. By type, the board carries 19 resistors, 17 capacitors, 12 ICs, 3 diodes, 2 connectors and 2 switches.
From the project
An 8-bit microcomputer for the 21st century
- ... independent: - contains all the tools required to design another version of itself - does not require high soldering skills, uses through-hole parts only - uses only "evergreen" parts that have been in production for decades and are still made today
- ... aproachable: - simple through reduction - NO hidden complexity behind brittle abstractions - open source and self-documenting
