Questions
How big is the Orchestrator interconnect PCB?
It measures 99.1 × 99.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Orchestrator interconnect use?
20 parts, built around the 74HC138 and 74HC74D. 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 Orchestrator interconnect KiCad files?
From the ksmonkey123/8bit_computer repository on GitHub, at the commit this page was made from: the board is circuits/pc-09_orchestrator_interconnect/orchestrator_interconnect.kicad_pcb and its schematic circuits/pc-01_dual_8bit_register/dual_8bit_register.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Orchestrator interconnect design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
