I was working on a Roland KR-370 that had been through a lightning strike, and I was looking for the BIN file to program onto a replacement EPROM (IC2). I did eventually find one, posted by a very helpful individual in the Badcaps forum.
During my search, I encountered several enormous repositories of EPROM dumps (such as this one at dbwbp.com, which is worth checking out), and decided to reproduce them on my website, should anybody need one. They’re listed below, and or you can download them from my file share.
This page offers a curated library of free EPROM dumps and OS ROMs for Yamaha, Roland, Korg, Casio, Kurzweil, and more. Whether you’re restoring a damaged keyboard, upgrading firmware, or preserving classic synth technology, these downloadable files can help you bring your gear back to life. Ideal for repair technicians, collectors, and DIY enthusiasts.
Reading and Writing ROMs
Although if you’ve found this directory, you likely know how to use it! However, I struggled to find a programmer that didn’t look like a cheap knockoff — at least that didn’t cost a fortune. I ended up choosing the XGecu T48, which costs about $80. As best as I can tell, this is the name brand device the other mildly cheaper options are based on.
