Re: How to remove CPU in sparcstation5?

@japes thanks, that obsolyte.com site does seem to have some decent info on the topic. Perhaps it is possible so. That says they run at up to 165MHz, not 160Mhz as given elsewhere. I can't say that bug would really put me off a TurboSPARC upgrade. Unless it will be a multiuser box or exposed to the ...

Re: How to remove CPU in sparcstation5?

Nice to see some SPARCstation 5 fans! Does a CPU-only microSPARC II upgrade on a socketed SPARCstation 5 system actually work (e.g. 70->85MHz, 70->110MHz, or 85->110MHz)? I've a socketed SS5 70MHz, and was on the lookout for an 85 or 110MHz chip to upgrade it (the TurboSPARC upgrades seem impossible...

Re: What happened to all the old Origin 200s?

I have about 6 O200 still collecting dust in my system cabinet at work. One is still running, a dual R12K/270MHz, the others are turned off and are in various state of cosmetic condition: i have about three intact doors. One does not exit POD due to a faulty dimm, the others should all be working. ...

Re: How easy is it to get HP-UX going for hobby purposes?

HP 712/100 is a nice machine. Low power, quiet, small size and good OS options. It runs HP-UX 10.20 and 11.00 pretty well, and 11i v1 explicitly included it as a supported system until the December 2004 release (perhaps later versions still work but are untested). Even so, 11i v1 is probably going t...

Re: archive.org -- SGI Software Library

OK, I downloaded a couple of disc images. Most appear to be good, but it appears some of them are truncated. .. Did you retry any downloads again just to be sure? I downloaded about 60 scanned PDFs of old DEC manuals from archive.org recently, but I'd say about 15 were truncated. On a second attemp...

Re: Low-level details of SGI multiprocessing?

Are there any known details on programming the ASICs responsible for managing the CPUs in multiprocessor SGIs? I mean, details from an OS-development point of view (ie: ASIC commands needed to create a new process on a certain CPU, or for scheduling each CPU, etc...). I don't mind if the details ar...

Re: Historic view on DEC Engineering

DECwest had some interesting technology in development (PRISM, Mica etc.) that sadly seemed to get canned for business/political rather than technical reasons. In one sense, part of the designs later made it into Alpha and Windows NT at least. Did you ever get to see any of that? Or did it even prog...

Re: HP C8000, Compaq XP1000 or HP zx2000

The zx2000 is a fairly rare and wanted system, in its niche of course. It's definitely a very nice system, as a rather quiet and energy-efficient one (compared to other systems in its class), which would accommodate a large number of platforms and fairly recent and up-to-date ones, too, I might add...

HP C8000, Compaq XP1000 or HP zx2000

Hi, I am interested in upgrading to a faster Compaq/HP UNIX workstation, so if anybody has one of the following machines they no longer use or want, let me know the exact specs and how much: - Compaq AlphaStation XP1000 with 667MHz CPU - HP C8000 with Dual Core 1.1GHz CPU(s) - HP zx2000 Itanium I'm ...

Re: SGI fibre channel disk array caught on fire

I had something similar happen to my Octane PSU last weekend when I plugged it in. You were lucky to find a replacement so cheap. The Octane PSU is unique and therefore seems to go for €140-200 as a spare part :-o It certainly makes me think twice about leaving my SGI's running unattended for any le...

Since you're clearly teetering on the edge of functional illiteracy, I will try and put this simply: no, you didn't. Relax. He posed some "devils advocate" questions and talking points, which in some circles might have led to some intelligent or interesting debate. Not many of us have Pri...

Re: unix books (Scholarly & Professional)

For the topics it set out to cover at the time, its a really excellent book. Obviously things have moved on, in terms of system architecture, processor architecture and kernel design. Many of the CPUs covered are gone, and some of the cache designs are no longer that relevant, but it still provides ...
