|AVL Multi-Image Slide Show Computers|
|In the '70s and
'80s, Audio Visual Laboratories (AVL) built a line of
computerized multi-image slide show computers that were more
or less the standard machines in use in the "A/V business"
at that time. I myself made a living programming and
staging shows with these from '84 to '96. Now, the
multi-image slide show business is history, and all of the
people who were involved in producing and staging these
shows are now working with other technologies.
||In recent years I
have unearthed my AVL gear: My Genesis from the garage, a
couple of Doves out of the attic. I found a bunch of
AVL manuals in the back of my office closet. I thought
it would be amusing to scan in these things and make them
available for those who can appreciate them (or, incredibly,
make use of them). Print them out, dust off that
machine and do some real programming for a change!
III Multi-Image AV Computer operator's manual:
This one is"old school" even for me - mercifully a few years before my time. Just thinking about programming a show with this thing is mind-bending to me. If you mastered this machine, my hat is (still) off to you.
is the 144 page AVL
Genesis Procall-X User Guide, the programming language
used by the AVL Genesis computer from the mid '80s forward.
have an AVL Genesis Board Set,
here is the installation guide.
Be aware that you'll need a mid-to-late-'80s-vintage PC
with an 8-bit slot!
This thing was designed to work with the computers
of it's time - a faster machine won't do.

Here is the only place on the planet to find an
AVL Show Pro 3 & 5 Service Manual!
(Thanks to Harry in NYC, who sent me the pdf!)
|Do you have an AVL Road
Is it complete with expander, external floppy drive and 5" monitor? I do, and am in the process of TRYING to bring it back to life. Here is the Road runner manual, which includes testing procedures to try if yours isn't running like it's 1981.

By the way, if yours IS working, and you've got working
road runner procall disks, please let me know!
|The AVL "Super Dove" was a
later offering from AVL and can do more tricks than I can
even fathom. I bought one; I have the manual; maybe I
will figure it all out someday.

2011 - A multi-image project!
This webpage led Renata Pedrosa, an artist in São Paulo, Brazil, to write and ask me "how to use a Dove to run a slideshow". She was building an exhibition and had in mind a 12 slide, 3 minute, looping slideshow - that would run for the 2 month duration of her event. After a bit of explaining about needing a programming device, positrak, and all the rest, I volunteered to program the show for her.
Here's how it worked: She sent me an .mp3 of the audio for her show. I built a simple program on my Genesis with 12 dissolves. I didn't have the slides, but set up a Dove and two empty projectors just to see the dissolves. I played her audio, analog, into one track of an analog/digital converter - and the output of the Genesis, looped through the Dove, into the other track (cueing the show in real time, to the audio), and captured them on my PC as a .wav file. I then emailed the file back.
She ran the file from an mp3 player, set to loop the track. One channel was audio for the speakers, the other, positrak for the Dove.
There was an appropriate pause and a HOME cue at the end of the track, to reset the two projectors. It ran great, for two months. Fun!
Here's her setup...
She was kind enough to include me on the wall leading into the exhibit!
Here's an image of the exhibition, from her website.
Look what I went and bought for $10 on ebay! It's an AVL Coyote. It looks brand new, and seems to work fine. I never used one of these things on a job (I think it was kind of low-end, relatively speaking). It can program a 3 projector slideshow, can "load" or "dump" cues to and from "mag tape", has a built-in Dove, and can input and output positrak. It can't make use of clocktrac, however.
The Coyote's interface - very '80s. Here is the next cue to be executed...
Here is the manual for the AVL Coyote! I recently found one!
A Cool Souvenir: December 2014
Bill Lewis of avtools.com presented me with this very cool coin, which apparently was a giveaway at the 1979 NAVA show.
Have a look!
December 2014: Look what I found!
I bought a chief stacker complete with projectors, lenses, a dove, and a "Travler" cassette player. The really interesting part is not the gear, but what came with it! A 3 projector slideshow, pitching multi-image (over film and video) as a presentation medium! Of course I wasted no time to capture it and post it to youtube, shot from a"programmers view". Make this fullscreen and HD!
