Questions

How big is the Pt8601 rom adapter PCB?

It measures 85 × 66 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Pt8601 rom adapter use?

13 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 Pt8601 rom adapter KiCad files?

From the inaxeon/PTV_Preservation repository on GitHub, at the commit this page was made from: the board is PT5XXX/PT8601_PT8631_Mod/Adapter_PCB/pt8601_rom_adapter.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Pt8601 rom adapter design in my own project?

Its repository states no licence, so its author keeps all rights: ask inaxeon before reusing the design.
