This adapter uses a CPLD to pass the RGB and sync signals from the Amiga 500 Denise socket to the Rasperry Pi Zero. It derives the pixel clock in a very different way to the c0pperdragon design and therefore does not require a jumper for Denise / Super Denise and has no “sparkling” pixel issues. It also has the advantage of being firmware upgradable if there are any issues found in the logic.
Refer to project GitHub page for software installation: is already flashed on the CPLD so that part can be skipped.
Board is professionally SMT assembled except for the Xilinx XC9572XL-10VQG44C CPLD chip that I’ve soldered by hand. CPLD chips are genuine, new and sourced from an authorized dealer.
Global chip shortage caused by the pandemic has raised the prices of the CPLD chips. Item price reflects that.
