As far as I know, they were only used in Ontario high-schools (maybe a few elementary schools). After they were pulled out of the schools, most were destroyed. Now they're unbelievably rare - especially
the original Burroughs Icon with the brown keys. After decades of searching, I have never seen any original Icon for sale.
My elementary school had them, well into the '90s so they may have been hand-me-downs from a high school that upgraded.

I distinctly remember the one in my grade 5 or 6 class being an Icon 1.
There are a few of them out there, but virtually all of the photos you see of them are turned off - probably because an Icon on its own is a lot easier to get hold of than the server & any of the software! AFAIK the desktop machines had no local storage at all - everything was on the server, so without that they don't do much.
I would absolutely love to see a web page or video that goes deeper into the software that was available on these. I think there was a fairly big library for them back in the day, but it's been really poorly preserved. I don't even think they've been emulated yet. Hundreds of thousands of schoolkids grew up messing with them so I'd figure there'd be at least a fair bit of interest.
If anyone here gets this (Snuci!) please figure out a way to dump the disks!
