the words together, as a phrase
sten OR sterling
either one (| works too)
sten -replica
leave out pages that mention “replica”

Without quotes, the last word also matches longer words that start with it (sten finds Stenophylla), and close word forms count (rifle finds rifles). Tick Exact words to match whole words only.

Whole deep dives are listed first, then the pages inside them.

    Volumes

    1. Vol 1 Aeon Dynamic Simulator — Volume 1 — Overview & the documentary record What the machine is, when it was built, and the unusual shape of its evidence — three photographs, no paper, and a front panel that turns out to be its own manual
    2. Vol 2 Aeon Dynamic Simulator — Volume 2 — The console and the patch field The physical machine, the bezel instruments, and the design decision that lets a machine with no surviving paperwork still explain itself — the legend that is a schematic
    3. Vol 3 Aeon Dynamic Simulator — Volume 3 — The computing elements Every element on the patch field catalogued from its printed legend: three summers, six integrators, six coefficient potentiometers, six diodes, a multiplier, the reference strips and the tie blocks
    4. Vol 4 Aeon Dynamic Simulator — Volume 4 — Inside the case The board stack, the semiconductor complement read device by device off two photographs, the trimmer banks and the letter-coded resistor system — and the precise point at which the absence of a schematic stops the analysis
    5. Vol 5 Aeon Dynamic Simulator — Volume 5 — Programming and scaling The ±10 V machine unit, the gain matrix the printed values generate, amplitude and time scaling, sign discipline on a machine where everything inverts, and two problems worked onto the actual hardware
    6. Vol 6 Aeon Dynamic Simulator — Volume 6 — Operating the machine The three-position lever, the initial-condition asymmetry as it bites in practice, the two readout instruments and what each is worth, the overload lamps, and a calibration sequence reconstructed from the test points
    7. Vol 7 Aeon Dynamic Simulator — Volume 7 — Context and the open questions Where a 1988 analogue computer sits among machines thirty years older, what it was actually for, and a consolidated ledger of every inference this series has made and the evidence behind each
