Wow. Josue Arias sent this to me. You can put this on the list of the rarest of the rare. I'm not one to benchmark rarity against, but I've never seen or even heard of one of these before. The only thing that comes up on Google is this site with a brief reference of the Driscoll. The Analog Heaven archives come up dry as well.
Josue refers to the Driscoll as a Driscoll/Serge modular. He states, "the 'serge' part is just because the similar modules in it (Slope generators, Random voltages, cv processors, Analog shift register,...) and because my system even have a serge 5 stage sequencing programmer!, but driscoll designed the same functions than the serge modular using another electronic aproach and design, so is not a clone(!)"
The Driscoll was built in the 70s by Australian composer/designer/engineer Julian Driscoll. Josue, believes the original Driscoll was a 10-12 panel system.
As for the sound?
"The sound for this synth is incredible, its really "organic", it sound like creatures more than electronics : ) I have it next to my 4 panel serge and I really like the driscoll sound a lot more."

"All the water drops/woodblocks/marimba/rithms, comes from the driscoll. I think it show the organic qualities. I`m ataching you a couple of photos but they are from my old studio"
Wow. Thanks for sharing this Josue.
Update:
Josue gave me the ok to post the following thread. Thanks Josue!

I`ve found some of the conversaions I had with australian composer

"Hello Mr. Burt,
I`m Josue Arias, a musician and sound engineer from Madrid(SPAIN)
I just got the old Segemodular tape from 1983, and I`ve found you have
a nice piece there called "You want, maybe, something a little intense
diatonic?"
