Main components
1README
audio-adapter/README.mdSharp PC-1251 audio adapter
The Sharp PC-1251 / TRS-80 PC1 audio connector lets you load and safe programs directly to a computer or phone.
It's easy to use and doesn't require a EC-125 or similar.
Most likely it also works with other 11-pin sharp models, but I haven't been able to test that yet.

Questions
How big is the Audio adapter PCB?
It measures 25.4 × 35.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Audio adapter use?
6 parts, built around the BC327. 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 Audio adapter KiCad files?
From the number42net/sharp-pc1251 repository on GitHub, at the commit this page was made from: the board is audio-adapter/audio-adapter.kicad_pcb and its schematic audio-adapter/audio-adapter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Audio adapter design in my own project?
Its repository states no licence, so its author keeps all rights: ask number42net before reusing the design.
