 *   **screen**: The default, per above.
 
 *   [**tmux**][tmux]: A popular alternative to `screen`, especially on
     BSD platforms.
+
+*   [**`dtach`**][dtach]: A minimalist alternative to `screen` which
+    provides only its terminal attach/detach features.
+
+    In addition to the virtues called out on the program’s home page,
+    use of this option has a side benefit for some PiDP-8/I users:
+    `screen` and `tmux` assume an [ANSI X3.64 terminal][ansit] (e.g. DEC
+    VT102 or xterm), because they interpret escape codes to provide
+    features such as their scrollback buffer. It is uncommon to find
+    PDP-8 software that uses ANSI terminal escape codes since almost all
+    PDP-8 computers sold predate that standard. Most PDP-8 software
+    assumes a dumb teletypewriter, and of the software that does make
+    use of a smart terminal, there’s a good chance it wants something
+    else, such as a [Tek 4010][t4010] series terminal. These ANSI screen
+    managers can therefore get in the way and mess things up.
+
+    `dtach` doesn’t interfere with terminal escape code handling; thus
+    this option.
+
+    Unlike `screen` and `tmux`, there is no command layer enetered
+    via an "attention" keystroke in `dtach`. The only key that `dtach`
+    scans for from the terminal is the detach keystroke, which we leave
+    at its default, <kbd>Ctrl-\\<kbd>.
 
 *   **none**: This mode is for interactive use, allowing you to
     run the installed simulator with the installed media without any
     screen manager at all.
