Fuck, a #Sun Ultra 25 for next to nothing, but pickup only. On the other side of Finland, literally. Damn.

@thomholwerda Since I know you're a fan of weird CPU architectures and have owned Sun machines in the past... Did you ever get a chance to use an UltraSPARC T1 or T2? The barrel processor idea has fascinated me since college, and I'd still love to get my hands on one of those. Maybe if I save up for a few years, I can try getting a batch made with wafer.space, since the hardware design is open source...

I lost track of how much equipment I used SETI@Home on for burn-in during the #dotcom era. It certainly helped my status on the leader board.

For 21 years, enthusiasts used their home computers to search for ET. UC Berkeley scientists are homing in on 100 signals they found. - Berkeley News

UC Berkeley’s SETI@home, one of the most popular crowd-sourced research projects ever, turned up some 12 billion signals of interest. A lengthy analysis found 100 worth another look.

I ran the Solaris version of this as a test. Loaded front page of Yahoo and then rejumpstarted workstation to scrub out the Microsoft.

A question for SPARC experts – did anyone use virtualization/hypervisors on SPARC v9/Sun4u machines, i.e. before the availability of Sun4v processors? If so, is there any sample code for a (ideally bare-metal "type 1") hypervisor available?

The only reference I found is a paper by Leon SPARC (v8) users who conclude that SPARC v8 should be classically (Popek/Goldberg) virtualizable using a trap- and emulate approach.

I just managed to pick up eight "Sun Netra 210" 1U UltraSparc-IIIi servers yesterday. In case any #retrocomputing enthusiasts here (particularly those of you I know personally) are interested in such equipment, please let me know. #sun #ultrasparc

I wish I had some more up-to-date #ultrasparc system(s).

Seems #linux #ultrasparc is getting some kernel tlc.

Just realised I now have an extra sparc compatible pci graphics card. And some quite nicely specced headlese sparc servers. Wonder if they could be combined to make a workstation? #ultrasparc #sunmicrosystems #solaris
