Moog Modular System III / Synthesizer IIIp (1969–1973, reissued 2018)
The record on the "Modular System III" is thin. No exact model by that name appears in period documentation. The closest and best-documented match is the Moog Synthesizer IIIp, a modular system that Moog released in 1969 and discontinued in 1973, reportedly because the machines were too expensive for most buyers. Its original list price was $7,985.
The IIIp was used by Wendy Carlos, Isao Tomita, Giorgio Moroder, and even The Beatles. Founder Bob Moog designed the system. Period context describes the early Moog Modular systems as enormous, expensive, and impossibly complex, with walls of patch cables, knobs, and blinking lights.
In 2018, Moog Music announced a reissue of the IIIp, handcrafted from all-original documentation, art, and circuit board files, and built with original parts in a 100 percent discrete design. Only 40 units were made, each priced at $35,000. The reissue came in three solid wood, tolex-wrapped cabinets with a switchable 350-watt power supply.
No detailed specifications on the original IIIp's voice architecture have surfaced in the available documentation. That means no oscillator counts, no filter types and no signal routing. The Moog manuals archive lists individual components like the 921 VCO and 904 VCF, but no complete "System III" entry appears in the visible portion of that list.
