Turbo -> wrote: Today was a good day for me: Got all of them for free. Anything for free is good, and there's enough stuff in here that would have been worth paying for. Is that a Tseng ET4000 ISA card in the third pic? And what's the middle card in the fourth - oddly small heatsink...?

P120: single, 3.3V P200MMX: dual, 2.8V Setting P120 at 2.8V is wrong, but it also means your mobo supports dual plane CPUs. Note that this doesn't matter - single-plane CPUs really only have one voltage plane, so Vcore is the same as Vio - so it doesn't matter what you set core voltage to, it will …

Was the PSU on at the time? If so, probably dead. If not, probably nothing to worry about so long as you are 100% sure it's dry before powering it on.

Came across one more SB16 I don't see listed here: the CT2840. Looking at it, it has a CT1747 OPL3 and Wavetable header. I can't make out the 1703 version though...

I like my AOpen MX3S as a good retro mATX platform, offers me decent 3d, sb pro compatible onboars ac97 codec as well as a decent amount of agp and pci slots. Obviously no PCI. I alao have a PC Partner PM601TMS3-T898C that I like for this job. No AGP but Blade3D graphics and sb pro ac97 onboard, …

Most of the better 386 motherboards made before 1992 used something called "bank interleave" for the main memory. The optimal configurations for these boards is 8 SIMMs. However, as far as I can tell they will always work with 4 SIMMs with a small performance penalty. As far as I can tell, nearly …

They had a whole range of boards with weird colours and odd gimmicks around 2000. A friend of mine did a pink fluffy cube casemod with a completely pink AOpen So370 (or maybe SoA, it's been a while ;) ) board inside. They started a few years before, iirc there was a version of the AX6BC in black …

Stupid question but have you tried reflashing the BIOs back to the known good one anyways? Maybe the board was originally used by an OEM with a BIOs modified in the backend that can't be seen. If it's not that or something failing I'm stumped. I did more than that, I physically swapped the BIOS …

Don't copper mines use a different voltage setting? I would think some sort of board revision that doesn't support it or a bad capacitor or something causing it to be too far out of specification to be the most likely cause. Yes, they run on 1.6-1.75V as opposed to 1.9V-2.1V. There is an earlier …

Testing time again today: - Went through a pile of IDE disks, with only two 40GB Maxtors (the least interesting in the lot) dead. The 6.4GB Seagate was working fine, which was the main thing. - Also some soldering: fixing caps on a motherboard and GPU. Both working now - an MSI MS-6168 Ver2 (uATX …

That TNT2-M64 should also be a dual-voltage AGP 4x card. If so the keying/voltage isn't the problem. What might be: the amount of power those other cards draw. Gf2 GTS and GF4 are pretty heavy by AGP standards, even the Gf4MX might be too much. I can find people mentioning that they have Gf2GTS …

Just tried downclocking the CPU, but that made no difference. EDIT: I have found an old AMD K6-II 550AGR too. 2.3V core/3.3V I/O, but I suppose that helps little. I'll have to order a CPU I think. Thankfully they are plentyfull. :) On the other hand, If I managed to find out what the different …

PCI/ISA POST card is ordered and should arrive in the next couple of weeks. I just remembered that I do also have a pentium 133, but that also has a different voltage rating then the MMX. And as you mentioned the board has no selector. It seems strange to me then that it does not autodetect. That …

Hi dionb, Thank you for replying so quickly! :) Yes, that picture of the PSU is very similar to mine. It has no mention of 3.3vdc, just like that one. Then that's one worry less: the lack of 3.3V is by design. My PSU no longer does anything. It made a dying rattle, and choughed and smoke came out …

Not too familiar with this specific machine, but maybe can help with a few general things. 1) Some early ATX boards were really only AT boards with a different connector and form factor and didn't actually use the 3.3V for anything. It's possible that that was the case here, and that Siemens decided …

I think I must have offended one of the gods of SCSI... I had an old Seagate Cheetah 9.1GB that wasn't being detected by my AHA-2940U2W. Probably a drive issue was my assumption, but neither controller nor cable were known-good, so postponed verdict until I could be sure. Today was the day to find …
