____ FRST CyberTerminal _______________________________________________

The FRST CyberTerminal is a hand-crafted e-ink personal computer.
It runs its own OS on bare metal — no Linux, no browser, no cloud.
Just a shell, your files, and the tools you need.

Built on Zephyr RTOS and inspired by Plan 9 from Bell Labs, the
CyberTerminal treats every peripheral as a network peer using the
9P file protocol.  Your keyboard, your data crystal, your neighbor's
deck — all just files in your namespace.
