Questions
How big is the Cpu input output control PCB?
It measures 221.7 × 33.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Cpu input output control use?
33 parts, built around the CD4060, 74LS04PC and 74LS173SC. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Cpu input output control KiCad files?
From the Trilobyte-CPU/8-bit-computer repository on GitHub, at the commit this page was made from: the board is PCBs/999-QUEUED-TO-PRINT/Backplane-IO-Controller/cpu-input-output-control-backups/cpu-input-output-control-2022-05-31_220220/cpu-input-output-control.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cpu input output control design in my own project?
Its repository states no licence, so its author keeps all rights: ask Trilobyte-CPU before reusing the design.
