Location footage was filmed in Sounth-Africa. Everything else was done in the amazing green screen facility at Stiller Studios in Stockholm, Sweden. The Cyclops MoCo system replicated all the pre recorded cameramoves, and final composit was a joyride.
Back in 1976, microprocessors had a maximum of 8.5K transistors for 64bits of memory. The Queen of England sent her first email, and Steve Wozniak designed the Apple I.
And a post-Star Trek but pre-TJ Hooker William Shatner made this film for AT&T about the future of microprocessors.
The chips were tiny at that time, to be sure, but paltry in terms of memory by today's standards. Yet Moore's Law had already been in effect for 11 years by this point, enough time to see that the future was going to be full of miniscule, powerful machines, even they weren't the predicted picturephones. Today's "microworld" is still getting smaller all the time.
This version of the film was slightly revised in 1980.
