• DEC Oral Histories

    From Lawrence D?Oliveiro@3:633/10 to All on Monday, March 09, 2026 00:29:03
    A recent addition to Bitsavers <https://bitsavers.trailing-edge.com/pdf/dec/history/> is a bunch of transcripts of interviews with various former DEC personnel.

    I?ve just been reading the Bob Supnik one. Why did I pick that?
    because his is a name I remember as the mastermind behind the
    well-known SIMH series of software emulators of
    historically-significant computer systems.

    But the interview is dated 1991, before all this. It talks about his
    career at DEC. On top of the fact that the audio was terrible, I think
    the transcriber was not familiar with the subject matter: the company
    name written as ?Xylog? could probably be ?Zilog?. And ?queue-bus? is
    obviously ?Q-Bus?.

    The first thing I think of when I hear Bob Supnik's name
    is Adventure (which morphed into Zork). I finally got my
    hands on the FORTRAH source code and ported it to run on
    the mainframe I was working on at the time (Univac 90/30).

    Adevnture is the Colossal Cave program (original by Will Crowther, fantasy elements by Don woods). It was always in FORTRAN.

    ZORK is the MIT Dynamic Modeling reaction to Adventure, written in a Lisp dialect called MDL ("Modeling Dynamics Language").

    Dungeon is what Bob called *his* port of ZORK to Fortran.

    See which way the morphing went?

    True. But I got hold of the source code for Dungeon and
    ported it too. The ports were challenging - I had to deal
    with ASCII-to-EBCDIC translation and work around DEC extensions
    to FORTRAN. But the biggest challenge was making terminal I/O -
    designed for character-mode terminals - work on the block-mode
    polled protocol that was typical of mainframes.

    Thanks for the clarification, Rich.

    I still have my username/password for Paul Allen's xkleten, where I would
    run the original version. Thanks for your work in making that available to
    us - too bad it's gone.

    I spent lots of hours on Dungeon under RSX-11M, some in the twisty
    little passages all alike.

    My early experiences on PC's and C64 systems was not particularly good, especially given that Zork was broken up into Zork I, Zork II, etc., so
    I appreciated being able to run the original version instead.

    While I also played Dungeon (and Zork) back in the late 70s,
    my favorite MUD was the Plato DnD application.

    For those who never got on-line at PDPplanet.com (later known as
    Living Computers: Museum+Labs), XKLeTen was Paul's first foray into retrocomputing with real hardware. It was an XKL Systems Corporation
    Toad-1 System (to give it the full marketing name), an extended KL-10
    clone running TOPS-20 v7.1. It was first featured on a late 1990s
    "Web 2.0" site called Paul Allen's Wired World.

    (This was, as it happens, how I met Paul Allen, when I sold him that Toad-1.)

    Around 2015 or so, we retired the Toad-1 hardware at the museum, moving
    all accounts onto a TOAD-2 which Len Bosack donated to the museum in
    advance of the grand opening in April 2013.

    I believe that all such accounts are still active on the TOAD-2, which
    is now part of the collection at the Interim Computer Museum, which has
    been discussed before (perhaps in alt.sys.pdp10, perhaps here).

    You should check, George.
