Snake running on a custom Z80 computer. Made for TEJ4MP.
Requirements
- A Z8400-compatible CPU.
- A TMM2016BP memory chip or compatible.
- A PCB with the KiCAD design[./PCB], or a breadboard with the equivalent schematic.
- An Arduino Nano.
Connect everything, flash the loader code with the Arduino IDE, and open web/index.html or https://creative0708.github.io/snakez80/ in a browser.
Have fun.
Building rom.hpp from source
You'll need a set of z88dk binaries with SDCC. Follow its installation instructions to install it.
Run make to build the ROM and convert the ROM into Arduino code.

Questions
How big is the Z80 snake PCB?
It measures 55.9 × 100.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Z80 snake use?
14 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 Z80 snake KiCad files?
From the Creative0708/snakez80 repository on GitHub, at the commit this page was made from: the board is PCB/Z80_snake.kicad_pcb and its schematic PCB/Z80_snake.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Z80 snake design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
