Recently, I’ve been looking for Windows drivers for a Bontempi PM 747 keyboard. As the official site has been useless for years, and Bontempi has been bought a couple of times, I had to go search the Internet Archive.
These drivers should be original. However, they don’t appear to work on a bare-metal Windows10 installation.
