Errata
Revision 1.0
- The clock pinout is messed up. If you already have a revision 1.0 board, solder single pin headers in to make it easier to connect up the clock can
- LCD footprint is too small. You can still try to solder in some wires, but this was initially intended for pin headers, so your mileage may vary.
- Interrupt lines are missing pullup resistors. Should still work unmodified if you don't use these, otherwise you need to wire botch wires instead.

Questions
How big is the Eater deluxe PCB?
It measures 214.2 × 149.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Eater deluxe use?
41 parts, built around the MAX232N, CD74HC00EE4, HM62256BLP-7 and SB140. 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 Eater deluxe KiCad files?
From the Red-Lucy-Engineering/eater-deluxe repository on GitHub, at the commit this page was made from: the board is eater-deluxe.kicad_pcb and its schematic eater-deluxe.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Eater deluxe design in my own project?
Its repository publishes it under the CC-BY-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
