    Are you pining for the days storage tube roamed the earth? At least
    there's an emulation here:

    Does this buy me anything significant that xterm in Tek mode does not?

    The appearance is closer to the original displays.

    Hasn't good old xterm done Tektronix emulation (4012 or 4014?) since
    like the 1980's (X11R3-ish)?

    Ah, so this is a bit more of a "simulator" then.

    Yes, it has.

    Oh, and also Tek4010 has some things xterm doesn't, like a "write-
    through mode". I don't know the details, but apparently it's a way to
    display short-lived graphics rather than persistant.

    Ah, so this is a bit more of a "simulator" then.

    I don't want to get into the emulator versus simulator semantics can of
    worms. I'll just note that neither xterm nor Tek4010 models the
    internal states of the machines, only the outwards visible behaviour.
    But the latter does so in greater detail.

    I think it's cool to do ARDS, a machine for which there is almost no
    software, data, or barely any collective memory at all.

    Nice! Compiles under FreeBSD if you change 'gcc' in makefile to 'gcc8'
    or 'cc' (clang).

    I am unsure if the xterm emulation supports GIN with a crosshair
    cursor.

    I don't want to get into the emulator versus simulator semantics can of >worms. I'll just note that neither xterm nor Tek4010 models the

    But the latter does so in greater detail.

    The 4010 has almost no internal state to model anyway. It uses no microprocessor and has explicit TTL logic to handle the escape codes.
    There's a few internal registers to hold things like the beam state,
    but not much.

    The Tektronix 4010 service manual will show you all the details. <http://manx-docs.org/details.php/5,18432>
