Commodore 64 Ultimate

Breadbin or Slimline, in BASIC, Starlight and Founders editions

The first official Commodore computer in more than 30 years. An AMD Xilinx Artix-7 FPGA recreates the original C64 hardware down to the chip level, so it behaves like the real machine rather than an emulator, with modern touches like HDMI, USB, Wi-Fi and more RAM.
