D10D3 built this “cyberdeck” on a C64c (a modern recreation of the Commmodore 64) with a Raspberry Pi CPU, VGA port, and all the I/O you could ask for (USB/Bluetooth/wifi/Ethernet).
But that’s just the hardware specs: what makes this great is the physical design — ooh, especially those stickers, seriously, shut up and take my money! — and the graphics.
