Questions
How big is the 6800sbc PCB?
It measures 188 × 193 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 6800sbc use?
164 parts, built around the 74LS42PC, 74LS259DC, 74LS00SC and 74LS04PC. 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 6800sbc KiCad files?
From the jefftranter/6800 repository on GitHub, at the commit this page was made from: the board is sbc/kicad/6800sbc.kicad_pcb and its schematic sbc/kicad/6800sbc.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 6800sbc design in my own project?
Its repository states no licence, so its author keeps all rights: ask jefftranter before reusing the design.
