I should have realized that it was Dilog. Interesting, I wasn’t aware that was due to Royalty payments that you had to choose between Tape, Disk, or Disk/Tape. That makes perfect sense. I can’t speak for Dilog, my experience is with the Viking boards (I forget how many names they were sold under).
With the Viking (Unibus and Q-Bus), you need the correct PAL, the correct EPROM, and you need the correct cab-kit that lets you log into the controller and flip a couple bits. I need to work on a power-supply or two for my PDP-11’s. I don’t really feel like letting the magic smoke out on my BA23 or BA123.
