From the project
Schematics of the Patinho Feio CPU being redrawn on KiCAD. More info at: http://github.com/felipesanches/PatinhoFeio
Para o desenvolvimento desse projeto estou atualmente (Julho de 2025) utilizando o Kicad versão 9.0.2+dfsg-1 instalado a partir do repositório de pacotes do Debian 13. ----
Existe um arquivo patinhofeio.pro na raiz desse repo que referencia os demais sub-projetos de cada placa.
Em JAN/2018 eu encomendei a fabicação das PCBs CDE-3 e CDE-3-debug. Há um relato detalhado em https://forum.fiozera.com.br/t/resgate-historico-do-computador-patinho-feio-usp-1971/58/18
