Esh
About the Esh PCB
Esh is an open source PCB design by RulecityLLC, published on GitHub under the BSD-3-Clause license. It is a 2-layer board measuring 299.7 × 229.9 mm, with 182 components from 81 distinct parts.
Other key parts include the 74LS253, 74LS86, 74LS08 and 74LS30. By type, the board carries 22 resistors, 10 connectors, 9 modules, 8 fuses, 7 diodes and 6 relays.
From the project
(Mostly) 1:1 clone of the arcade game PCB for the Funai game, Esh's Aurunmilla
I became fascinated with this game some years ago and desired to own one. Unfortunately, the PCB and laserdisc are both exceedingly rare. So instead of finding originals of these items, I created reproductions. I created a mostly 1:1 clone of the game PCB which is what this repository consists of. After selling 20 of these clones to collectors and exhausting commercial demand, I decided to open source the whole thing for preservation. What you have in this repository are the results of my efforts.
