Jamie Idolpx has shared a quick demonstration of the TeensyROM Serial API using Python. In the video, he shows an early script that communicates with a Commodore 64 or 128 through the TeensyROM cartridge. The script already works well, though a few quirks remain.
Exploring the Script in Action
The video shows how the Python script interacts directly with the TeensyROM hardware. At this stage, it already allows useful communication between a modern computer and a Commodore system. Idolpx mentions that some refinements are still needed, but the script is nearly ready for release once cleaned up.
Why This Matters for C64 and C128 Owners
For C64 and C128 users, the Serial API opens up valuable options. Developers and hobbyists gain the ability to test commands, control cartridge features, and extend functions from a modern machine. While this preview is short, it makes clear how flexible the TeensyROM can become.
Getting Your Own TeensyROM
Anyone interested in trying the TeensyROM Serial API can find details on GitHub. Updates and documentation appear there regularly. The cartridge itself is available for purchase, giving owners of C64 and C128 hardware direct access to these features.
Idolpx plans to release the script after more refinements. Until then, this demonstration gives a strong sense of what’s coming next. It shows the continued growth of TeensyROM as a useful tool for retro enthusiasts.
