A project to allow Williams System 7 pinball machines to automatically upload scores to a website.

This repository has code and design files for the device that taps into the pinball machine's bus, and the web application that receives and displays the scores.
None of the code here is production quality, it's purely for reference and inspiration.

Questions
How big is the Internet connected pinball PCB?
It measures 70 × 55 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Internet connected pinball use?
11 parts, built around the 74LVC245AD. 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 Internet connected pinball KiCad files?
From the elipsitz/internet-connected-pinball repository on GitHub, at the commit this page was made from: the board is pcb/PCB.kicad_pcb and its schematic pcb/PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Internet connected pinball 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).
