Hi

I have uploaded into the Matrix Doc's folder the specification files for the Matrix-6 (1986), Matrix-6 and 6R (1987) and Matrix-1000 (1987 without the color picture).

I also have the specification files for the DMX, DPX1, DX, Stretch, XK keyboard, Prommer, Oberheim price list 1987 and 1988 and 2 pages ad presenting the Oberheim Line in 1987.

I will upload these files if someone is interested.
