Questions
How big is the CassetteSDK-85 PCB?
It measures 127 × 80 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CassetteSDK-85 use?
33 parts, built around the LM324AD and MJ-3536N. 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 CassetteSDK-85 KiCad files?
From the ForNextSoftwareDevelopment/8085 repository on GitHub, at the commit this page was made from: the board is Kicad/CassetteSDK-85.kicad_pcb and its schematic Kicad/CassetteSDK-85.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CassetteSDK-85 design in my own project?
Its repository states no licence, so its author keeps all rights: ask ForNextSoftwareDevelopment before reusing the design.
