century

A ternary magnetic computer, developed slowly. The basis is the Setun, and the constraint is a machine that is still serviceable and reproducible in a hundred years, not one that is fast now.

Documents

• logic-element.md the wound ferrite threshold cell, from Setun book chapter VII
• core-memory.md the threaded core store, from chapter X
• seed.md what a unit that reproduces itself must contain, and what it must stockpile
• ref/setun-1965/ OCR of the primary source, page markers included

Status

Design notes only. No hardware, no schematics, no bill of materials yet.

Scans of the primary sources are held outside the repository, deliberately. See the sources section of core-memory.md for where they came from and why they are not committed.
