PicoGraph gives ISA-era PCs a path to modern displays by converting legacy graphics output through USB DisplayLink, targeting retro users who can no longer easily find MDA, CGA, Hercules, EGA or even VGA monitors.
The adapter is built on a PicoMEM ISA card with a Raspberry Pi Pico handling the translation, while software does the heavy lifting for MDA, Hercules, EGA, VGA and a 1990s Cirrus Logic SVGA chipset.
DOOM appears to run through the setup, showing the system can handle more than basic text or early graphics modes on vintage hardware.
The project fits a broader retrocomputing trend in which 2020s microcontrollers extend old machines, replacing scarce peripherals with modern interfaces.
As microcontrollers revive vintage PCs, what classic hardware will be resurrected next?
How does reviving 40-year-old PCs change our understanding of computing history?
Is using original hardware with modern adapters truly better than pure software emulation?
