The other two brochures

The two remaining brochures from the order wouldn't go through the Epson — tri-folds, and the feeder jammed on the folds every time. So they went page-by-page onto the HP OfficeJet's glass at 600 dpi instead. Honesty about what that buys: half the resolution of the paper manuals' scans, and a fold line through the middle of every spread. The two pages that join across each fold have been reassembled in the published PDFs, seams matched against the printed panel photos.

Worth it. The orange one — Otari's Compact Professional Tape Recorder tri-fold — carries the footer B-103A-9-75: September 1975, which makes it the earliest piece of factory sales paper on this site, from the era when the four-channel QX stood in the spec table beside the two-channel machines. The blue one is the April 1978 re-set, S-117A — the same pitch re-typeset, ordering information for the FL, 2SH, 2SL and servo 2SHD, specification figures that quietly moved: 65 dB where 1976 said 68, crosstalk 55 where it said 60, and — for once — a sales sheet that names the alignment tape it measured against. The cover page pairs the blue title panel with the introduction column, the same two-column design as S-111's own cover face. The differences are tabled on the specs page, with the usual warning about comparing numbers that weren't measured the same way.

A previous owner pencilled "USER" across the 1978 brochure's cover and punched both for a binder — this paper was somebody's working reference, not a showroom leftover. Both are transcribed verbatim as digital editions, joined spreads and all, on the manuals page.
