Prophet-10 Owner's Comments
2009 email from Kevin S. regarding two Prophet-10s that were recently
repaired & restored by Wine Country - including a MIDI kit installation:
"Thanks so much for the really terrific work you did on my two Prophet 10's.. they are both great.. captured my imagination.. just massive and powerful.. blew me away. A pleasure doing business with you.. I would be happy to recommend you to anyone, please feel free to have them contact me if anyone should need a "first-hand experience" reference."
Prophet-10 OS & Diagnostic ROMs
The Prophet-10 Operating System consists of 3 ROMs. OS Version 4.0 is for Prophet-10s with the front mounted EXCITRON tape drive, Version 5.0 is for Prophet-10s with the side mounted Braemer tape drive, and Version 6.1 is for all Prophet-10s with MIDI installed. A MIDI kit installation will permanently disable access to the EXCITRON tape drive and sequencer, but the Braemer tape drive and sequencer will continue to operate with MIDI installed. The 3 socketed MIDI OS ROMs are labeled as 0, 1, and 2.. and can be seen in the adjacent picture. The MIDI ROMs are labeled 0TEN6.1, 1TEN6.1, and 2TEN6.1

Version 6.1 Operating System is ONLY for a Prophet-10 with MIDI installed.
The 2-chip Diagnostics ROM set also downloads the factory programs into memory, and works in any Prophet-10 regardless of tape drive type, MIDI or no MIDI. The 2 ROMs are installed into the OS socket positions 0 and 1, & position 2 remains empty. The ENABLE/DISABLE switch on the back panel must be set to the ENABLE position in order to run all diagnostics routines AND install factory programs into memory. The Prophet-10 Diagnostics is available for $28.95, with basic instructions also included.
