Today I had to buy some new hardware because a piece of retro-chic I'd had for the past decade died on me - my trusty old 3Com 3CGSU08 Gb switch died on me. Even though the Zyxel GS1200 that replaced it is superior in every way - managed, 60W 802.3at PoE and even so lower standby power usage - it …

I've seen LIF sockets on some industrial So5/7 SBC boards, so not impossible. But to join the chorus: pics! Not so much for the actual CPU (we'll take your word for it you don't see any more than the CPU with something plastic under it) but to identify the rest of the situation/board. That might …

I was looking to see what kind of board, just didn't find a number.( I like the smell of old boards. :) ) Those old PB boards don't have the model no printed on them, but there is invariably a P/N starting with 67xxxxxxx that you can google, or otherwise use these tips: http://www.uktsupport.co.uk/ …

L1 you mean... a Pentium doesn't have L2 cache on-die, and the cache on the motherboard is fine as other CPUs show.

Recently I acquired an Aztech Sound Galaxy Waverider 32+ (I38-MMSN826) as an upgrade to my old Sound Galaxy Pro 16 II (I38-MMSN824). It's basically the exact same AZT2316A-based card, but the Waverider 32+ has an ICS2115 WaveFront synth chip added for extra General Midi goodness. At least, it would …

Well, not really. They also wanted to copyright the SLOT. They couldn't copyright PGA, so to prevent AMD from fitting into Intel boards... Yes I know Slot A is just a backwards Slot1, but it was enough to keep amd off intel boards, and keep companies like VIA from making 1 chipset for 2 cpu's. Slot …

Older systems had BIOS limitations on hard drive capacity (varies by chipsets as well). My Socket 7 system only recognized up to 32GB, and anymore than that, then it gets detected as a 7.8GB HDD. My Packard Bell Pack-Mate 28 Plus does the same thing as well (2.1GB limit instead), but when I updated …

Yes, it's a bit ambiguous between title and topicstart. If it's a low-end P4 style 350W PSU instead of a mid/high end Athlon style I see the challenge - but even so this should be fine, although you really want a PSU that delivers most of its current on 5V for a system like this. Good thing good …

The CPU gets its power from the 5V line, as with other pre-P4 designs. 12V is only used for keeping drives spinning, so you really don't need much there. It should be fine. Let's turn the question around: *why* do you think 120W on 3.3V and 12V combined won't be enough?

Interesting. Can you post some pics of the motherboard as well? Just to make sure the oscillator is the through hole version and not the SMD. Not right now, as it's bathing in vinegar. But it's definitely through hole - on the top it wasn't clear whether a component had been removed or never …

Testing yesterday's haul (slowly due to a bout of the flu). The known good boards are indeed good, but that poor PB430 LPX So3 board is in worse state than I first saw.
