Penn & Teller’s BBS – MOFO EX MACHINA


  • 2019-09-27: Here is an interesting read about Penn Jilette’s time writing for PC Magazine, which mentions his BBS and links to this post.

Before the public Internet and the World Wide Web, there were computer Bulletin Board Systems (BBSes). A device called a modem (modulator/demodulator) would turn computer data in to audio tones (modulate) so it could be sent across a phone line, and the modem at the other end would turn these tones back in to data (demodulate).

My first exposure to BBSes and modems was thanks to a local Radio Shack in Houston, Texas. They let me use their TRS-80 Model III to dial in to BBSes around the city. The salesmen there turned me in to part of a sales pitch. “This young man is currently connected to a computer across town…”

I never had a modem for my first computer, a Commodore VIC-20 that I received in 1982. I did, however, get to borrow a modem (from that same Radio Shack salesman) to use with my Radio Shack Color Computer I bought in 1983. That modem was a 300 baud (very slow, about the speed of a really fast typist) acoustic coupled version, which was the type with round holes on it that you would set a phone handset in so it could play sound to the mouthpiece, and hear sound from the earpiece. That’s right — you had to dial the phone yourself then set the handset down on the modem when the computer at the other end answered! (There were “smart modems” by then that could dial and answer the phone — that’s what the BBSes used — but they were vastly more expensive. I wouldn’t have one of those until years later when the price came down.)

But I digress.

Over the years, modem technology evolved, and they got faster and cheaper. BBSes were operating everywhere, and I remember calling them as late as 1995-1996 or so after I moved to Iowa. By that time,dialup internet was starting to spread, and soon calling a local BBS would be a thing of the past.

I miss my BBS days. I wrote one in 1983 that a cousin of a friend operated in Houston for awhile, and I ran my own several years later elsewhere in the state. I even started it up again (briefly) in Iowa. It was a fun time, and there was a greater sense of local community on them since most users would be from the local area (avoiding long distance charges).

Magicians Penn & Teller had a BBS of their own, too. It was called MOFO EX MACHINA. The following is a transcript of a dialup session I had with the system on November 24, 1990. Set your wayback machine to 300 baud (but hopefully 1200 by then) and read on:

         count something filed here as "Recorded Diem" until you
         are notified to do so by your supervisor.

         We would like to thank those brave enough to help us
         work out the in-operatives in this system.  Remember,

      Hello, and thanks for logging on.  This is Teller.  I'm writing
this installment in a hotel room in Baltimore on November 10th, 1990.
We're touring this fall, and this is my fifth hotel room, if you don't
count the one in Chicago by the ice machine that I moved out of so that
I could sleep.
      I am reading SUNDAY NIGHTS AT SEVEN the Jack Benny
biography/autobiography.  In dark type is interesting stuff from a
manuscript by Benny.  It's nice, good-natured stuff about the life of a
vaudevillian, radio star, and tv personality.  In light type (the bulk
of the book) is petty crap, poorly written (dictated into a tape
recorder?) by his smug, talent-free adopted daughter.  Oh, boy, at last
she has the chance to brag about being a spoiled brat and get back at
her demanding mother.  Unfortunately, every once in a great while, she
quotes George Burns or somebody else good; so you can't get away with
just skipping the light type.
      The tour is going gangbusters.  It's a bit eerie.  We land in a
new city.  We drive into town.  We walk into the theatre, which is
always distinctly different from the last one.  And there on stage is a
little microcosm that is absolutely the same:  our set.  It's almost as
if somebody picked up everything in my bedroom, even the waste basket

full of trash, and placed it, exactly as it was, in the middle of the
      My happiest extracurricular activity:  I heard a great band in
Milwaukee, The Rhythm Club.  Four women and a bass player who are all
amazing musicians and who, like NRBQ seem to be able to do ANYTHING they
want at the drop of a hat.
      Upcoming events -- Letterman on November 20th.  Our big special:
"Don't Try This At Home" on the 23rd.  Minneapolis, San Francisco, Los
Angeles, then a short vacation.  Ta for now.

What's up with Penn - 11/20/90

Well Mofo computer friends,  

I'm on an airplane flying to Minneapolis where we'll do our show
for a few nights.  I'm writing this on my Grid 1450SX, a major cool
computer that I get to borrow because I'm writing the back page for
"PC Computing" magazine.  The issue on the stands right now has an
article of mine on the back page with a little drawing of me.  The
picture is okay - my fat smiling face sitting at a computer but the
computer has a sticker that says, "Kiss Me, I'm User Friendly". 
I'm sorry, it was not my idea.  They didn't show it to me before it
was printed.  As a matter of fact this whole article was edited
heavily but they promised that won't happen in the future.  I've
asked Pie to get my original one on this machine so you can check
it out.  I've written my next four back pages already and you can
tell because the vast majority mention Uma Thurman.  That means I
had to have written them before I saw "Henry and June" where Uma
doesn't feature her Thurmans.  Since then, I don't talk about her

12 min [?,C,G,M,Q] --> C

much.  I hold a grudge.  I'll try to get all the "PC Computing"
articles on-line here so you can read them without having to buy
"PC Computing" but you have to promise that if you read them here
you'll write a letter to "PC Computing" and tell them how much you
liked my articles and how because of them you'll buy the magazine
from now on every month.  They've had someone cancel their
subscription and write a nasty letter because I'm too violent.  I
need your help.

We've been on TV a lot pimping the "Penn & Teller: Don't Try This
at Home" - If you have a Nielsen box, please watch it and nothing
else that whole week and if you don't have a Nielsen box, use your
own judgement.  I think it's a good special and if it does well,
they'll let us do it again.

This is the first thing I've written in a long time for the Mofo
machine.  Since the Wall Street Journal talked about it we're
trying to get it up and keep it good so, if you got any ideas - let
us know.  I'll be writing stuff for this area pretty often from now
on and maybe I'll even write something good but right now I'm on an
airplane and you know how that is.

I'll have a diet cola, no glass, no ice,

I'll look into it and let you know why.

Penn & Teller, with the help of MOFO the Psychic Gorilla have
gone under, way under, to develop a fan club for all of you out
there who know these boys are onto something big.  Yeah, you'll
get bimonthly newletters, discounts on wild t-shirts, records,
tapes and videos, and someday (after they're out of style), there
may even be a button.  Gives you chills, huh?  You'll learn how
to swindle and humiliate like a pro, talk a blue streak about
funky new strains of music, pull crack-up jokes out of thin air.
Hey, you'll learn how to be cool.  This club's not for wimps or
Doug Henning/David Copperfield fans (redundant), your stomach is
probably not strong enough to join.  Think it over carefully.
Then GET DOWN, and send six dollars to:

No, there is no electronic mail for now.  Talk to the Evil
Overload SweetiePie about this if you wish.  Don't bother
me, I just do as I'm told, when I feel like doing it.

There should be some fresh stuff on the board soon.  The
email probably won't return until I figure out a stable way
for it to operate, and perhaps not even then.

We're thinking about it.

November 1990:

Someone called in and trashed all the files on the hard drive.
We're not sure why, but we've taken some measures to make it a
little more difficult.  There are two announcements here, each
written by Penn and Teller.  Soon there will be a way for you to
write to them.

That was almost 25 years ago. Hopefully one day we can hear Penn tell us more about this BBS, and how it started and ended. Drop by Penn’s Sunday School (audio podcast) and drop him a note and maybe, if there is enough interest, he will make it a topic for an episode.
