I was checking out some newer episodes that were posted of the classic computing public television show "Computer Chronicles" and I found this particular episode with coverage of the RDI Halcyon and the Pioneer MSX laserdisc game system. I don't recall seeing this footage before and the pacing of the show is kind of slow, but it's the only footage I have ever seen of Rick Dyer actually demonstrating the system. It's kind of awkward but interesting. Check it out...
