Landing page captured for the 2026-09-05 issue.

Field notes

The intake form grades calculators across functional, cosmetic, and provenance-related details, including dead LCD rows, missing keycaps, battery corrosion, slide covers, and school asset tags. It names TI-84, TI-Nspire, TI-89, Casio fx-CG50, HP Prime, and NumWorks among its examples, and supports quantities from one unit to a 10+ bulk lot. The displayed workflow says the quoted amount remains locked for 14 days, subject to the calculator matching the submitted description.
