Questions
How big is the E8Serial PCB?
It measures 125 × 113 mm and has 2 copper layers, 1.6 mm thick.
What parts does the E8Serial use?
53 parts, built around the AY-3-1015D, 74LS37P-E, 74LS04PC and 74LS123FP-E. 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 E8Serial KiCad files?
From the ibm2030/EDUC8 repository on GitHub, at the commit this page was made from: the board is E8Serial/E8SRT/E8Serial.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the E8Serial design in my own project?
Its repository states no licence, so its author keeps all rights: ask ibm2030 before reusing the design.
