Hmm I suspect the computer isn’t the issue here but rather the os you are trying to use with it.

You might be right; then again, that's the whole point of this build.

NT 3.1, Windows MME (3.0a), and OS/2 2.x only have audio drivers for ISA-based sound cards, so I wanted a super fast motherboard that still had full capability for ISA sound. The G7S620 was one of the last boards made with fully functional ISA slots.

All of these OS's run just fine with a variety of PCI graphics cards (the ones I noted in my previous post) on my G4V620 with a P4 2.8GHz and 2GB of DDR-333 memory. I frankly expected the G7S620 to boot and run each OS the same, just faster (the presence of integrated SATA ports and a real AGP slot would have been icing on the cake). Unfortunately, a number of my PCI cards had issues on it. Very frustrating.

Nice find!👍 Any idea why the lower ISA slot is missing?

Yeah, my friends and I were wondering the same.

Does not appear to be missing components from other versions that have the second slot.

Oh, that looks like the connector has been desoldered. The through holes are a little damaged and one via on the left took a bit of a beating from what looks like someone leveraging the connector with a flat head screw driver but it doesn't look like anything is too damaged to just solder a new connector back in.
Makes me wonder why this board was chosen as a donor. Have you tested it yet? Fingers crossed for it to work!

SB Pro 2 CT1600 - Two of them! On the same day! How does that even happen?

Two different revisions of the SBPro2 CT1600 and the left one has an oscillator crystal onboard to boot! 😁

That's interesting. I'll be honest, I don't know what it means though. Does it make them different in any meaningful way?

Not sure, but it looks like the one with the oscillator is a later revision (based on the serial number). So, they must have added it for a reason. A quick glance of my SB collection, it seems that all models since this SB PRO 2 revision have this oscillator except for the AWE64(GOLD). Earlier models do not.

The ISA slot was definitely desoldered, otherwise the holes in the board would have been filled with tin solder.

I got this Acer MAGIC S30 a while ago on eBay. Not super cheap but not really expensive either. Some of the nuts and bolts where a bit rusty and overall the card was a bit dirty so I gave it some TLC (a spin in the dishwasher and rinse with lots of IPA), tested it today and it works like a charm.

The onboard oscillator crystal helps to avoid timing issues between the motherboard and ISA bus.

The A500 is a very solid case and certainly not cheaply built, but hey, everyone is entitled to their opinion. To each their own.

Compared to the cheapest options from this era - yes, it's pretty solid, but compared to the case mentioned in this thread or some other quality options like Enlight EN-7230 for example, yes, it's pretty cheaply built.

Like I said. Everyone is entitled to their opinion. I had both of those cases, at one point, in multiples. The Enlight case you mention, in my opinion, was nowhere near as solid of a case as the A500. This is a niche hobby with many options to choose from. As long as you're happy with what you have, that's all that matters.

Opinions - sure, but what I'm saying is a matter of fact not the matter of opinion - build quality, material quality and so on are very easy to compare you know. It's not like I'm saying one looks better than the other or something like that. 😀

CREATIVE! Sound BLASTER! 16!!! SCSI!!!!!!!!!!!! CT1770.

Delivering EARTH shattering sound quality! Prepare to have your socks blown off! (not). 😁

Damn animals ... though, belive it or not I still have a plan to rescue this basket case. Some time down the line an episode will pop up on my thread. 😁

Okay cool. Thanks for enlightening me.

Now every time I hear an audio bug on the card without the oscillator I'm gonna wonder if that's the culprit. 😁

Typical case of someone going mad while trying to install Creative drivers and wanting to save others of the same fate...
Not that improbable imho.

Besides that it's in very good condition. Very clean and tidy. Almost like new. You should be proud of owning one like that!

Looks like the poor card was in the middle of a gunfight! Or someone was annoyed at the MIDI hanging note bug and used it as target practice...

It is an early SB16 variant where it isn't complicated to install the drivers.

I am wondering if it was some warranty policy either from a distributor or retail, or higher in the pipe, faulty cards get the drill.

Why would anyone want to destroy these cards? These are clearly destroyed on purpose.

My hunch is that they wanted to test it for precious metals but I think that even the use of a torch to remove the chips would've been way better. All is not lost though. Two holes are in the ground plane and the traces on the third are easy fixes. If I find a donor I'll scavenge the chips. Someone told me that usually on these old cards the layers are mainly ground so I'll try to see what's what. 😁

L.E. Or maybe they held classified sounds from the DN 4ever that actually was never released?! 😁

It arrived today, I wasn't looking for this model but a simple Sound Blaster 16. Instead, I found this on a sales site at a price that was not very low but not even close to the stellar one found on Ebay. Going back to the Sound Blaster, some say it's the spearhead of OPL cards. The card is incredibly long and unexpectedly does not reach the case supports…
