The communities biggest interest would definitely be a clone of that drive, as currently Xenon OS is still oddly private. Would be a huge help to get more info and accessibility out there to people recreating their own alpha kits.
I remember reading about this...so cool :'D https://forums.macrumors.com/threads/power-mac-g5-alpha-xenon-kit.1833169/ User shinda here talks about an ISO from 2001... https://www.betaarchive.com/forum/viewtopic.php?t=33201 And here are all SDKs, Xenon and Natal as installers : https://mega.nz/#F!voIzCAjQ!FoAE6zLRzo2QAoBCDP5dPg
i think the latest a alpha can use is 1600 somewhere close to that idk the exact numbers but you need more then just a recovery to get them to boot they certainly are a interesting beast
Oh, that's really cool that this could help people researching this hardware. I didn't realize there was so little documentation on this. I'm hesitant to install anything new on it, but I'm happy to try photographing some of the guts and seeing what I can do about powering it on for you all. It's kind of buried behind stuff at the moment (that's a photo I took a few months ago), but I'll try to get what you're asking for.
Normal power cord, USB mouse & keyboard and a DVI to VGA adapter is all that's needed. Before powering it on please open the side panel and confirm there is no white residue on the bottom of the case, if there is do not power it up.
The cooling system in these towers fail and leak. Video cards are spec'd out in other threads here on AG but the search system lacks. Edit: ATI X800XT 256MB was one of the 2 cards used.
that's right the early g5 heatsink's were water cooled I keep thinking that they were made by Delphi you can covert them to air cooled if anyone needs them I have the apple G5 service manuals
The PowerMac G5 model used by Microsoft for the Alpha G5 kit was not liquid cooled. Only the 2.5 and 2.7 GHz DP models had it and were prone to failure (the later PowerPC 970MP Quad Core model had a better liquid cooling system).
At least back then Apple used to stand behind their products. I had one of those machines with the leaky liquid cooling system that was stuck in the dark at the back of my desk and I never realized it until I turned it on one day and the power supply went bang. So I took it into Apple to get a repair quote (since it was well out of warranty and I didn't have Applecare) and they called me up about a week later and told me I could come and pick it up - they had done a free-of-charge swap with a new system and just transferred the HDDs and RAM (both of which were undamaged) from the old one. I'm sure if the same thing happened today they would find some way to weasel out of fixing it.
Even the Apple of then probably wasn't supposed to do that, I'm guessing you got lucky with your local store. @Kao Anyway, back to the G5 kit: yes people are still interested! As others have said, it's best to take the side off and inspect the system for residue before powering it up. Maybe show us some photos too if you can.
