The devil is in the details. "Little differences" could mean the difference between working and smoking. Smoking isn't going to happen here, Vcc corresponds, as does Vss = GND. Next the I/O lines are labeled 0-7 on the Inova datasheet but 1-8 on the NEC one. That's probably more naming convention …

"Supply Voltage" is the relevant value here. This says it needs 5VDC+-10%. So any similar 5V chip would work fine. If a chip indicates "Min 2.97 Max 3.63" then it's a 3.3V part and might get fried. So long as the Max is 5.5V it will be fine.

That Tasmania 3D is a truly interesting piece of hardware. Utterly pointless though - makes the 3D Blaster VLB and NV1 look well supported by comparison. But that's part of the charm (there's a reason I have SSI-2001 and AdLib Gold replicas 😉 ). Hope you still have both kidneys.

It didn't just affect low-end stuff, a lot of high-end good quality designs also suffered from it. Antec in particular had some highly regarded PSUs that …

[...] I think they're equally stupid, if we solely consider their actual 'usefulness'. The V5 6000... is just a buggier and more power hungry V5, that will probably run a few games at higher framerates (and those games will run a lot better on a cheap GeForce 4 Ti), and will outright refuse to run …

That, plus: - there are more AdLib Gold cards out there. - the actual number of use cases for an AdLib Gold are smaller than a V5-6k (a handful of old games vs anything that will GLide)

Thanks for the valuable input so far Does the 440BX board use the 12V rail to some extend so that some of the load can be offloaded to that? To some extent, although pre-2002, the 12V line was mostly used for motors (e.g. on drives). But we're talking 29W per P3-1000E(B) CPU, total 58W for two, …

Slight point on the salaries: to us Europeans salaries upwards of USD 100k sound impressive - but there are huge differences in taxation, pensions and benefits, which mean that you need a higher gross salary in say US to obtain the same standard of living as in Europe.

Hmm... your symptoms are related to data integrity, but you've tried multiple I/O controllers, multiple drives, different RAM and a different CPU. That leaves two suspects: 1) L2 cache. Try disabling it and see if problems go away. 2) UMA. The chipset shares memory bandwidth between CPU and VGA. …

As for the knob: no, it's just a mechanical part to make it easier to turn the pot. Not too sure about the wire, but it is on the schematic, so probably a good idea. Mine is buried deep in a case I can't reach right now, and my pics aren't clear on that part, so can't check what I did exactly.

-5V is used on the ISA bus, mainly to power some sound cards. I'd expect that PB to have a 3rd gen Azetch card. I'm not sure whether it needs -5V, I know some older Aztechs do and some newer ones don't. Worst case that card doens't work. You can get AT-ATX converters that also do -5V to be sure. I'd …

Rare as hen's teeth, and most likely from the very end of AT case production. Probably industrial/rackmount cases are your best bet.

Pretty sure this isn't NLX. In NLX systems, the edge connector is on the side of the motherboard and the riser has the 'slot' that plugs into it. Here the (PISA-like) connector is on the top of the motherboard and the edge connector is on the riser. So this is a totally proprietary combination of an …
