The C128DCR ROM options have received fresh attention thanks to a new update from World of Jani. The Commodore 128DCR supports both 2364 and 2764 type EPROMs for the character ROM (U18). This flexibility is controlled through jumpers J15, J16, J17, and J18 on the main board.
Jani’s own C128DCR includes a Swedish and Finnish character ROM variant. That version has now been dumped and published online. Searching for the identifier 325181-02 previously returned little information, so sharing it publicly makes this resource much easier to find.
World of Jani’s post highlights how jumper settings determine compatibility between ROM types. By adjusting these jumpers, owners can select the correct configuration depending on whether they use a 2364 or a 2764 EPROM. This detail is particularly useful for repair work or for users wishing to experiment with different regional character sets.
The release of the Swedish/Finnish ROM fills a gap in preservation efforts. While many regional variants of Commodore ROMs are documented, some remain rare or difficult to source. Adding this version ensures collectors and enthusiasts can more easily access accurate dumps when restoring or studying hardware.
For anyone maintaining or modifying a Commodore 128DCR, the availability of this ROM dump offers both technical guidance and a reliable reference file. It demonstrates once again how sharing detailed documentation helps keep retro computing hardware accessible for modern users.
