2 X Eproms with latest firmware version 2.0 for Masterboard and version 941205 for the Voiceboard for Oberheim Ob-Mx

Features/improvements:

  • Bug fixes related to midi communication and system code issues.
  • Improved envelopes

Bonus:

The Calibration firmware also included in this kit, which make you able to calibrate your Oberheim OB-mx. The procedure requires an oscilloscope and an expansion card that provides access to the motherboard when the power is on. Many "technical services" have this kind of card and are quite capable of performing the procedure.

Note:

  • Fully verified before shipping and professionally packaged in anti-static material.
  • If you have more than one voiceboard installed, please contact me before buying due to that it is recommend having the same Voice OS on all the voiceboards.
  • IC socket on Voiceboard is located at U5
  • IC socket on Masterboard is located at U7

Factory Initialization:

I would recommend to perform a factory initialization after installing the main OS and the new voice OS.

Hold both keys, while you power the Oberheim OB-Mx
