Buchla Electronics Musical Instruments 200e: USB Utility Card
NoiseBug Price : $99
NEW LOWER PRICE!
Occasionally, we make changes in a module’s firmware to fix software bugs or to add new features. The little firmware cards we used to supply with modules have been replaced by the USB Utility Card. With a Macintosh computer running OS10.5 or higher, you can load the USB card from the web, and then transfer the firmware to the module.
