Questions
How big is the ISA Card PCB?
It measures 138 × 96.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ISA Card use?
161 parts, built around the 74HC125D, 74HC368D, 74HCT244D and 74HCT245. 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 ISA Card KiCad files?
From the AkBKukU/CM153-Repro repository on GitHub, at the commit this page was made from: the board is EDA/ISA-Card/ISA-Card.kicad_pcb and its schematic EDA/ISA-Card/ISA-Card.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ISA Card design in my own project?
Its repository states no licence, so its author keeps all rights: ask AkBKukU before reusing the design.
