Hi Guys,

When I was working at Oberheim back in the Mid to Late 1970's we built a few
custom 4/8 voice synth's for customers like Jan Hammer and Patrick Moraz. I
wish I had a digital camera back then. I was digging around in the garage
last week end looking for some of the custom sequencer's I built at Oberheim
and wondered if anyone was interested in seeing a Photo of this Mechanical
add-on to the sequencer.

At on time I personally owned 4 8-Voice Oberheim units. One of these 8-voice
units was a Black panel with white letters and Black Natural key's and white
Sharp/Flat keys on the 5-octave pratt-read keyboard.

Alas, all that remains is the Balck Keyboard in my garage. If anyone see's
the Black SEM based oberheim on E-Bay send me a picture.

I still have some PPG and E-Mu modular equipment but I have not powered them
up for over 20 years I bet.

Just a non-sequitor input to custom stuff.

Best regards,

Terry Sgultz
