One ROM

Flexible ROM replacement for retro computers using a Raspberry Pi RP2350 microcontroller.

Physical productfreeglobal

One ROM is a free, open-source hardware project that replaces failing or obsolete ROM, EPROM, EEPROM, and PROM chips in retro computers with a single Raspberry Pi RP2350-based board that drops into the original chip's footprint. It's aimed at retro computer collectors and repairers who need a flexible, modern replacement instead of sourcing hard-to-find period-correct chips.
