SSH client, local shell, and terminal emulator for classic Mac OS 7/8/9.

A fork of ssheven by cy384, expanded into a full-featured terminal environment.

• Multi-window: Cmd+N opens independent windows, each with their own tabs
• Tabbed sessions: Cmd+T for local shell tabs, Cmd+S for SSH tabs, Cmd+1-8 to switch
• Local shell: built-in command interpreter with 30+ commands
  • File operations: ls, cd, cat, cp, mv, rm, mkdir, touch, and more
  • System info: ps, free [-h], df [-m|-h], uname, date
  • Mac-specific: getinfo, chown, settype, setcreator, chmod, label
  • Tab completion, command history (up/down arrows), colorized ls output
• SSH client: password and public key authentication, known hosts verification
• Scrollback: Shift+Page Up/Down to scroll through history (100 lines per session)
• Copy/paste: mouse text selection with Cmd+C/V
• Telnet & raw TCP: telnet host [port] opens in a new tab; nc host port for raw TCP inline
• FTP client: ftp get user@host:/path, ftp put user@host:/path file, ftp ls user@host:/path — PASV mode, progress bar, glob uploads
• SCP file transfer: scp get host:/path, scp put host:/path file — password and key auth
• wget: wget http://... and wget ftp://... — one-shot file downloads with progress
• 256-color & true-color: xterm-256color with RGB support via Color QuickDraw, bold, italic, underline, reverse video
• Symbol font: custom bitmap font for box drawing, block elements, shading, and geometric shapes — seamless rendering at all font sizes
• Color themes: load iTerm2-compatible .sttheme files, or use built-in Dark (Tango) and Light palettes
• Configurable: font size, display mode (color/monochrome), foreground/background colors, prompt color, terminal type string

• CPU: any PPC processor, or at least a 68030 (68040 strongly recommended)
• RAM: 2 MB
• Disk: fits on a floppy
• System: 7.1 or later (versions below 7.5 require the Thread Manager extension)
• Network: Open Transport required for SSH (local shell works without it)

SevenTTY supports custom color palettes via .sttheme files (16 ANSI colors plus background, foreground, and cursor). Use the Preferences → Theme... button to load a theme, or select the built-in Dark (Tango palette) or Light modes.

To convert an iTerm2 color scheme:

python3 tools/itermcolors2sttheme.py MyTheme.itermcolors > MyTheme.sttheme

Copy the .sttheme file to your Mac and load it from the preferences dialog. The theme persists across launches.

Hundreds of iTerm2 themes are available at iterm2colorschemes.com.

Requires Retro68 with Universal Headers and cmake.

Dependencies (mbedtls, libssh2, libvterm) are pulled in as submodules and built automatically.

mkdir build-m68k && cd build-m68k
cmake .. -DCMAKE_TOOLCHAIN_FILE=/path/to/Retro68-build/toolchain/m68k-apple-macos/cmake/retro68.toolchain.cmake
cmake --build . --parallel $(nproc)

The script build-fat.bash can also be used to build a fat binary.
