I haven’t tested this. This is just my upload from the DodgyPLA project:

Description:

Commodore 64 PLA replacement

Based on the work by skoe:

This design uses the Xilinx XC9536XL, which has 5V tolerant inputs essential for operation with the Commodore 64.

As opposed to skoe’s design, the required CASRAM delay is implemented in Verilog instead of using additional components.

This project includes:

A Xilinx ISE project written in Verilog for Xilinx XC9536XL A KiCad project including a board designed for home etching

This is my feeble attempt at making back button pads for a Gameboy Zero Build.

My thinking was to make something that would work for both a tactile button or a membrane style button setup.

If you are using a tactile switch/button you will need to insulate it from the pad.

Also I have no idea how to build PCBs so this is totally a stab in the dark. Proceed with caution….
