Questions

How big is the Parallel adapter PCB?

It measures 39.2 × 32 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Parallel adapter use?

4 parts. 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 Parallel adapter KiCad files?

From the simoninns/valiant-turtle-2 repository on GitHub, at the commit this page was made from: the board is kicad/acorn_userport_adapter/parallel_adapter.kicad_pcb and its schematic kicad/acorn_userport_adapter/parallel_adapter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Parallel adapter design in my own project?

Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
