"I found an old Matrixsynth post [here], did a bit of research and contacted Dieter Doepfer for additional info. Find my post at [link] Most interesting IMHO":
"Dieter: 'To some extend this was also the beginning of the Eurorack standard (instead of Doepfers/DD Systems earlier Formant sized modules) as the front panels already had the same dimensions and mounting positions as the A-100 that started in 1995.'"
"Up for sale is a vintage, all original, un-modified, very gently used, 1973 ARP 2600 series "2600P V3.0" analog synthesizer and "3604P" keyboard. This is an incredible, all original model for a musician seeking to purchase a vintage ARP 2600P. There are no missing pieces, and there have been no alterations. It has been recently cleaned, serviced, and calibrated to factory specifications.
This version of the ARP 2600P contains the infamous and sought after ARP 4012 filter (see photo).
The keyboard, had new factory specification rubber bushings installed for each key, restoring the action of the keyboard to "like new" performance standards. The keys work perfectly with aligned, even-tempered action. All of the keys are intact, un-chipped, with no cracks. A few of the white keys at the low end of the keyboard, have some staining (see photo).
The face of the console and keyboard have a few, very minor, scratches. The black vinyl exterior of both road cases that house the console and keyboard, are scratched and torn from normal wear and tear. Both travel cases are original and structurally sound with the original handles and clasps (tarnished) in excellent working condition. This console and keyboard have matching serial numbers: Console: Ser# 261523 and Keyboard: Ser#: 361523. The set includes the ARP 2600 console and 3604P keyboard in their original travel cases, the original gray power cable and gray console to keyboard cable, 4 patch cables and, the original ARP 2600 sound effects patch book."
