Hi Ram, I just "lucked into it" - The original owner had given it to a museum, however when they closed they returned it to him due to it's unique nature. He wanted to put it somewhere where it would be preserved and found me! As fortune would have it, we in the same province (about 6 hours away). The history the owner gave me might make you cry however. He was working for a company in Toronto who had about 20 of them shipped over from Germany and either never used them, or used them only for a short while. They were all stacked up in a storeroom for "years" and someone decided it was time to clean out "all that junk" - He snagged one, but he's pretty sure that most or all of the others got landfilled. - The one I got is "like new", and in it's original shipping box ... I expect the others were the same :-( Thanks - I guess it just looked so "unixey" that I expected a shutdown command. I've grabbed most of the docs, and I will be going through them in detail. So far I have NOT replaced the original OS. The distribution disks say version 1.1, IIRC I saw a version 1.17 somewhere on the screen but I wasn't taking notes at the time (just trying to get it to come up). Next time I fire it up I will record the details of what is there. The file structure looked pretty clean (like a system that hadn't seen much use at all) - pretty much just basic system utilities etc. I will at some point try the Helios 1.3 that you have posted, however I don't want to wipe the original drive, so I'm going to dig around and see if I can find a compatible hard drive. Thanks again - you may not have heard the last of me ...
