the '70s and '80s, Audio Visual Laboratories built a line of
computerized multi-image slide show programmers 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, multi-image is dead, slides are dead, and all of the people who were involved in producing and staging these shows are now working
with other technologies.
Now my Genesis is somewhere in the garage, a couple of Doves are in the attic. I just unearthed a couple of AVL manuals from the back of
my office closet. I thought it would be amusing to scan in some of this stuff 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.

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 out of an mp3 player, set to loop the track. Mono audio to the speakers, positrak to 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.
Addendum: December 2011
Look what I went and bought for $10 on ebay! 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 drives 2 or 3 projectors, and can "load" or "dump" cues to and from "mag tape", and output positrak. At least I think it can. And, I do not believe that it can "hear" clocktrak. At least I think it can't.
Here is the manual for the AVL Coyote! I recently found one!
The Coyote's interface - very '80s. Here is the next cue to be executed...
