THE CLONE-HUNTING GAME
For years we’ve listened to the community and delivered safe, modern replacement PSUs and accessories for Commodore systems. Thanks to continuous feedback from C64, C128 and Plus/4 users worldwide, every revision gets better. This adapter follows the same philosophy: reliable pin-mapping, robust connectors, and long-term durability—designed by active 8-bit users.
We’re proud that our original Electroware designs have become a de-facto industry standard. Sadly, some products have been copied and simplified by sellers chasing “easy” profit—often trading safety for looks. Please beware of clones; we cannot guarantee their quality, protection features or long-term performance.
Perfect add-on for our C64/C128/Plus4 PSU PRO models!
