FRST: MODEL4 — What's Inside
==============================

Manual         46 manual pages, on the deck itself.
               `man cmd` reads one, `man -k word`
               searches, `help` is the short list.

Shell          ZRC — rc-compatible shell with pipes,
               variables, scripting, command history
               Three shells at once (F1/F2/F3)

               vi, sed (stream), p (e-ink pager)

Networking     9P file protocol over BLE, LoRa, and TCP
               BBS client — rooms, messages, files, chat
               Gopher client — read and post, bookmarks
               Telnet with ZMODEM file transfer
               FTP, netcat, finger, ping

Mesh           Æther — LoRa radio, no towers, no carrier
               Peers found by name, not by address
               `who` for the roster, `chat` to talk

Identity       Your name is bound to a key this deck
               generated and never sends.  No password.

Games          Tetris, Snake, ZZT, Chess, Blackjack,
               Wumpus, Hangman, Arithmetic, Fractal

               Integer BASIC (type 'woz' to try it)

Tools          Todo, calendar, address book, images,
               slide presenter, phase of moon, Morse,
               fortune, typing trainer

Programming    Forth — the deck's own environment, with
               words for the shell and the namespace,
               editable on the machine (frst.fth)

Hardware       ESP32-S3 @ 240 MHz, 8 MB PSRAM
               7.5" e-ink 800x480 B/W display

               8 MB persistent filesystem
               Firmware updates over the air

Philosophy     Everything is a file.
               Every peripheral is a network peer.
               There is no app store.
