We had a family friend in the 1970s who had one and I used to go visit and spend hours on it. I was using PETs every week at the same time so it was a bit of a shift to a floppy-based system and one that had 3 CPUs on top of that! I started fiddling with PDP-8s about 4-5 years later and was surprised to learn there was a PDP-8-on-a-chip (IM6100 then later then IM6120). Very cool that you've made it available now. I just don't think I'll ever run across a Challenger 3. I haven't in the past 30 years, and I live about 2 hours from where they were made. Was the original 560Z a popular board? I'm guessing it was a niche product. -ethan
