ProphetŪ10 OS & Diagnostic ROMs
The Prophet-10 Operating System consists of 3 ROMs. OS Version 4.0 is for Prophet-10s with the front mounted Exatron 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 Exatron 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

The Prophet-10 Diagnostics is available for $29.95, with basic instructions also included. 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.

Sequential Circuits ProphetŪ10 & MIDI
This restored Prophet-10 sn#0322 had a working original built-in Poly Sequencer and factory MIDI kit, and it was rated in excellent electronic and near excellent cosmetic condition. The cpu & audio electronics were calibrated to factory specifications, tantalum capacitors in the power supply were replaced, and a new memory back-up battery was installed along with factory programs. Then it was subjected to well over 100 hours of operational burn-in prior to assure reliability, and it shipped in an original factory roadcase with casters. To assure reliability every Sequential Circuits instrument sent to Wine Country for repair and/or restoration undergoes this very same process.
The Prophet-10 and all Rev 3.x Prophet-5s use the exact same analog voice board. The exact same powerful & warm analog sounds that can be created with two Prophet-5s can also be created with one Prophet-10.
As with the Prophet-5, the Prophet-10 is 115/230 VAC voltage selectable.
Prophet-10 Owner's Comments
2009 email from Kevin S. regarding his two Prophet-10s that were 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."
