The Ultimate Collector’s Package: Serviced & Ready to Play
Up for sale is a beautiful 1984 Sequential Circuits Six-Trak (Model 610, Serial # 610-004885). This six-voice, multi-timbral analog powerhouse has been meticulously serviced and upgraded. Unlike most loose units on the market, this incredibly rare package includes the original factory shipping box, the original protective foam, and the original operation manual.
Upgrades & Servicing
Modern NVRAM Installed: The original internal battery system has been completely bypassed and professionally upgraded with Anarchy 6116 NVRAM modules. Your patches stay locked in permanently—zero risk of battery acid damage to the mainboard, and you will never need to open the case to swap a battery again.
Factory Presets Restored: The memory bank has been freshly initialized and reloaded with the authentic 1984 Sequential Circuits factory patches via SysEx.
Fully Tested: The onboard membrane matrix, parameter controls, and MIDI connectivity have been verified and are fully functional.
The Collector's Provenance
Original Packaging: Includes the original heavy-duty Mark Container Corp box (manufactured in San Leandro, CA) and the highly elusive custom-molded blue foam endcaps.
Original Documentation: Includes the original Operation Manual, complete with the fold-out voice block diagrams.
Vintage History: The original box still bears a fantastic vintage shipping label from "Music Emporium USA" in Rockville, MD.
Condition & Shipping
Cosmetics: The synthesizer presents beautifully with only light, appropriate wear for a vintage instrument of this era (see photos for exact condition).
Logistics: Packaged and shipped with extreme care by Magic Cardboard Ride LLC. We understand the value of original packaging, so the factory box will be safely packed inside an outer shipping box to ensure it is fully protected in transit.
