Oh geez, I hoped I could run that on the Amstrad PCW 8256 of my dad, although I'd still would have to get it on a 3" not-that-floppy disk. :lol:

Re: Anyone know the pinout for the Sun Cobalt Qube2 PSU ?

Great, just got the same box. What is original amperage for PSU? 3.0 A , see the attached photograph of the label on my working PSU of my second Qube 2. cobalt-networks-qube-2-psu-label.jpg Alternatively you can also power the Qube 2 via the internal connector that usually powers the hard disk (see...

Re: Cobalt Thread

Poking this thread. Over the weekend I sat down with my original MIPS RaQ to try johnnym's suggestion with the load resistor , except that while trying to rehabilitate the board I ended up snapping the battery off. Same here, except I did that with the battery of my CacheRaQ 2 (I believe). I think ...

Re: New Octane, odd issues

Just had a thought here. I have a spare O2 riser card with the TO-92 style chip. It would be an interesting experiment to tack it onto my Octane frontplane and see if that works. Such a shame that chip failure is bringing down the whole machine. Why don't you try to put the NIC of your dead Octane ...

Re: What Apple hardware do we have?

What OS is it running? If OS 9, Sonnet Metronome can often get an accurate clock speed, or CPU Director if it supports it. If OS X, what does System Profiler think? Sorry for not replying earlier, but I didn't recognize your answer until today. Looks like I didn't got a notification for your answer...

Re: I'd like to build a (micro)cassette tape unit

If I understand you correctly, you want to build a Datasette ? I believe there might be a lot of information available about these devices. The References section of the Wikipedia article could be a good start: ⋅  How TurboTape Works ⋅  How Commodore tapes work ⋅ [...]

Re: Part 5 of my History of SiliconGraphics series is done! Any thoughts?

Once I get the parts from Ian. The Indys have broken graphics cards (we think) and the Indigo2 has a hard drive but as far as I can tell the drive doesn't work. It might also work to netboot the Indigo² from one of your working machines. I once netbooted my Octane with loader, kernel and FS served ...

Re: [ebay][uk] 4 x Sun SPARCstation 5 - not mine

Yeah, I copied and pasted it the URL into an existing ebay.co.uk page and it came up in English. I then took a look at their other auctions and thought why buy one when you can buy 2? ;o) I see, so you bought two of the TurobSPARC driven SPARCstations "only". I first assumed you bought tw...

Re: some sun servers on gc surplus

Not a lot of super cheap T1000s on ebay right now, but there is a T2000 with an optical drive...add a 2.5 SAS drive and you're good to go... Using SATA SSDs could be even more speedy and a good extension for hosting logical domains. Something I still have to try on my T1000. I wasted lots of time a...

Re: Indigo 2 video output to vga monitor?

that would also imply that the first two cases of (3) could be combined, if you don't use pin 3 of the 13W3 connector. I believe the DDC connection is one direction, monitor to system, and so is the function of the 4 monitor ID pins. As far as the cable/adapter goes this should be irrelevant. An ol...
