# 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.
