This microcontroller just made ROM programming obsolete - The OneROM!

Vintage BIOS replacement made easy? In this video I take OneROM for a spin on my IBM XT and a turbo XT clone -- swapping out the original ROM chips for this clever open-source microcontroller-based replacement. This video is sponsored by pcbway.com - for all your PCB assembly, CNC machining, sheet metal fabrication, 3D printing and much more, head to https://pcbway.com ! OneROM emulates 24, 28, 32 and 40 pin EPROMs and mask-programmed ROMs found in nearly every home and personal computer from the late 70s through to the early 90s. The best part? A single board covers multiple ROM types, and you can reflash it directly from your browser in seconds. We look at how it fits into the XT socket, how to program it using One ROM Web, and what it actually runs like on 40-year-old hardware.
