Accutrac 3500R
Documentation specific to the Accutrac 3500R is almost nonexistent. What little can be said with confidence is that the 3500R appears to be a variant of the Accutrac +6 system - the model 3500 that Accutrac promoted heavily in the late 1970s as a computerized, six-record turntable with programmable track selection. The "R" suffix likely indicates a minor revision or regional variant. No period literature has surfaced to confirm what distinguished it from the base 3500.
The better-known Accutrac +6 model 3500 sold for less than $300. It used microprocessor control to let the listener play tracks from up to six records in any programmed order. High-Fidelity (July 1978, p.18) described its computerized track selection, and noted that the same circuitry and electro-optic mechanisms would have cost over $100,000 to build from scratch just a few years earlier. A conventional changer drops records onto the platter. The +6 used an "Accuglide" spiral spindle that lowered each disc gently, and Accutrac emphasized it in its advertising as a key selling point.
If you own a 3500R or have come across a service manual, sales brochure, or review that mentions the "R" specifically, the Archive would welcome the correction.
