Those of you who've been reading this topic know that I'm considering buying a Socket 7 motherboard. I have one but I killed it in a moment of negligence.

I'm in Belgium. There is nothing on my local second-hand and auction site. A comparable Dutch site has a few broken boards and maybe one that would cost me an arm and a leg.

So I looked on eBay, which was when two things became all too clear to me: (1)Socket 7 boards have indeed become a rare breed and (2)people still want to sell them for like $100. I'm expecting those two elements to be limiting factors.

This seller, located in Latvia, has some motherboards of this type in stock for a still somewhat reasonable price. They claim to have tested all of them and confirmed them to be working.

They listed the board in this auction as a DTK PAM-0057V E0. According to stason.org, this board exists in three versions (3.01, 3.02 and 3.03). Version 3.03 looks most like the board in the auction, with the exception of the FP header. That is to say, I can't find the FP header on the image uploaded by the seller.

However, I do see the FP header on a photo of the same board in another auction: right between the CMOS battery and the side of the board, as indicated on the page on stason.org.

So did the seller in Latvia incorrectly identify their board? Is (could) the board they have (be) another version of the DTK PAM-0057V E0? Or another model altogether?

I focus on the FP header because I'm inexperienced with connecting these cables to their corresponding pins. It's not the meaning of something simple like "HDD LED" that is a mystery to me; it's the variety in labels for the different FP header connections what can confuse me. Not to forget the fact that the layout of a specific (version of a) board may be difficult to find.

Where do I go from here? How can I find an interesting and tested to be fully functional Socket 7 motherboard for a reasonable price that someone who is not specialized, such as myself, can install without much trouble?

No clue, not a fan of DTK boards. Things in Europe are different than my area, mostly much cheaper. Not sure why you cannot find a good socket 7 for $50
ok just rambling and am very tired

Hate posting a reply and then have to edit it because it made no sense 😁 First computer was an IBM 3270 workstation with CGA monitor. Stuff: https://archive.org/details/@horun

It looks like the 0057V and the 0075V EO are a little bit different. Here's another seller with a 0057V EO which matches the one on Ebay, and has a clear photo of the model number on the board. Both of these boards have a DIP switch, which the one on Stason does not.

It doesn't look like a bad board, but I have no experience with that brand. It's too bad that boards like the Asus TXP4 have gotten to be so expensive since they work very well with a wide variety of CPUs and memory.

I just found an auction for a Kaimei Jamicon KM-T5-T1 on eBay. Tested and fully functioning. And for a reasonable price.

The board has both four SIMM and two SDRAM slots. Apart from some SDRAM modules on my Pentium 3 machine, I don't have confirmed good RAM modules. The seller told me he has modules of both types in stock. SDRAM is faster, so if I do buy the board I would opt for two modules of this type.

I can clearly see the FP header connections on the images provided by the seller. This page has a scan of the board's manual. The board's CMOS chip is powered by a CR3032, which is what I prefer.

Those who have been reading my topics know that I'm not a specialist. So I'd like to ask your opinion on this board. Seems like a good buy?

I see some bent pins near the keyboard port.

That usually indicates that the hardware hasn't been handled gently, to put it mildly. It may still work, just figured I'd point that out.

PC#1: Pentium MMX 166 / Soyo SY-5BT / S3 Trio64V+ / Voodoo1 / YMF719 / AWE64 Gold / SC-155
PC#2: AthlonXP 2100+ / ECS K7VTA3 / Voodoo3 / Audigy2 / Vortex2
PC#3: Athlon64 3400+ / Asus K8V-MX / 5900XT / Audigy2
PC#4: i5-3570K / MSI Z77A-G43 / GTX 970 / X-Fi

I hadn't noticed this. Thanks for pointing it out.

The seller claims in the description that the board looks like new, as if it only recently left the production facility. The description is in Italian, which I understand quite well.

They have two boards of this model for sale.

EDIT
The seller claims he found the board to be fully functioning after testing.

Also, in case you're not aware, there are (non-super) Socket 7 motherboards which have an ATX power connector.

Usually those based on the Intel 430TX chipset.

Note that that board has an i430TX chipset. Generally it's one of the best So7 chipsets, but there's a big mismatch between supported RAM (256MB officially) and max cacheable area (64MB). Uncached RAM is slower, so you don't really want to use a board with this chipset with more than 64MB. A single 64MB PC100 DIMM is best memory choice for a board like this.

If you really want more RAM, go for an ALi Aladdin IV, V (G-revision or later) or Via MVP3 (with 1MB of L2 cache) board instead.

Do all motherboards based on the 430TX chipset have an ATX power connector? Or do boards based on this chipset with an AT power connector exist?

The Jamicon board you linked to only has the AT connector, but others (such as the TXP4) have both.

Power connectors aren't related to chipset. In theory any chipset can have any power connector. They are related to form factor:

ATX boards must have an ATX power connector.
(Baby)AT boards must have AT (P8/P9) connectors. Some late ones have ATX connectors.

The first ATX systems date to 1996 (Intel's Advanced/ML 'Marl' motherboard is generally credited as being the first), but AT systems were still being made up to 1999ish. Because the ATX standard required +3.3V power and soft power on, no (standards-compliant) ATX boards were made with AT power connector, but there's nothing stopping an AT board getting power from an ATX connector, provided it has provisions for the soft power on. So AT boards from the last year or two (from late 1997 on) frequently had an ATX connector to allow you to use a then new ATX PSU.

Bottom line: if you want an AT board with ATX power connector, look for ones from 1998-1999. Although if you want to use an ATX PSU, why not go for an ATX So7 board?

Thanks for the info.

I don't have a spare ATX power supply at the moment. That's why, basically.

My recently acquired Jetway J-TX98 has the AT form factor and had both AT and ATX connectors. It's some hybrid between socket 7 and super 7 as it supports the K6-2 including it's pretty low voltage, but officially "only" does 75MHz fsb (unofficially 83 as well). My super 7 Asus P5A-B and PC chips M577 are AT and also have both connectors.
So yeah, this is not too common, but there are enough available.

Concerning your search: I suppose you're checking Marktplaats already. Also keep an eye on Tweakers. There also are some nice boards for sale from time to time and mostly for even less expensive than Marktplaats.
