Tang Nano 9K FPGA board turned into $15 retro PC running Doom
A hobbyist known as ThePartsBin built the system around a Gowin GW1NR-9C chip and also ported Tyrian, System Shock and Ultima VII to it.
A hobbyist known as ThePartsBin has configured a Tang Nano 9K FPGA board as a retro-style computer, running a RISC-V CPU at 36 MHz on the board's Gowin GW1NR-9C FPGA, according to hackaday.com. The chip provides 8,640 LUTs.
The system offers 8 MB of RAM, HDMI output, 48 kHz stereo audio, two USB ports and an SD card reader. ThePartsBin also ported four 1990s games — Doom, Tyrian, System Shock and Ultima VII — which run at 720 x 480 resolution.
The Tang Nano 9K typically costs around $15, putting the whole build in the range of a budget single-board computer rather than a dedicated retro hardware purchase.
