About this directory

What belongs here

newold.computer catalogs hardware that gives an old computer a useful new capability, keeps an important part working, or helps you find a worthwhile period upgrade.

Reverse Retro covers the opposite direction: modern-host tools for preserving old media and reusing vintage components and peripherals.

New commercial upgrades you can order.
Open source projects you can build.
Discontinued products with useful documentation.
Vintage upgrades worth searching for used.
Modern-host preservation and reuse tools.

Console modifications are intentionally outside the current scope.

How it is checked

Listings prefer maker pages, official stores, documentation, and project-owned repositories. Availability and compatibility are dated.

There are no affiliate links. A used-market link is a durable search, not an endorsement of one listing.

A directory, not a guarantee

Old computers vary by board revision, region, firmware, and previous modification. Read the maker's current instructions before buying or installing anything. A listing is a research lead, not a substitute for electrical and compatibility checks.
