Local craigslist and couldn't resist.

that is awesome congrats

Bought this non working Asus NCCH-DL workstation board, super cheap with two Xeon 3.6Ghz/1/800 cpu.

it's a dual socket 604 with Intel 875p chipset and agp pro slot.
the only reason board wouldn't post was the bulged caps on buck converter for the ddr memory rail, there were other bulged caps across the board but they weren't that critical to make the board not post.

this is the ultimate i875 set up for me that has decent build quality compare to desktop socket 478 boards with the same chipset.

I was looking for a KT333 motherboard, but instead this listing turned out to be a Super Socket 7 board - the 1st one I have owned since 1998. A loose 256K async cache module was also included. I thought the fan was bare, but attached was a bill for building a 486, heh!

Wow, that is quite a find. An odd one at that - the silkscreen on that cache module suggests it's an M919 specific 5-volt cache module but the cpu is 3.45v. Maybe it was used with the CPU running at a higher voltage so that cache could work?

A nice HIS Radeon 9800 Pro 128 MB with an Arctic Cooler cooler I got locally for cheap 😀 The exact same card I had about 20 years ago! Mine died from faulty memory chips.

So I grabbed another "parts or repair" GeForce 6600 Universal AGP. This time just the normal non-GT version, built by PNY. This one was listed as working and displaying video, but with a bad fan. That was a lie, but not in the way the seller likely meant.

It works flawlessly. You know when the fan doesn't spin? When the Molex power isn't connected, because again these universal AGP 6600 pull 100 percent of their power from the Molex. Its not like well literally every other card I know of that will display an error message or beep if the molex isn't connected. These just do nothing.

So the seller thought the card was completely dead, decided to lie and list it as working but with a bad fan, when in reality it works perfectly but he was too incompetent to discover this. Hence how I got another AGP 6600 for $25.

I also got around to testing the $5 Quadro FX3500s, and one of them worked, one of them was completely dead, and the other had issues and someone had already tried to reflash it to a 7950GT. Now as you might imagine, reflashing a 450MHZ 20 pipe G71 card with 256MB of memory to a 600MHZ 24 pipe card with 512MB of memory didn't work out that well. G71 on PCIe is laser cut, so there is no reenabling pipelines on these. I reflashed it back to Quadro 3500 but either it already had issues or the 7950 flash blew out a memory chip because it was still artifactin like a mofo. For $5 each shipped I'm not complaining 🤣 I knew what I was getting into with that purchase.

Two days ago, I bought this motherboard for my favorite AMD K6 processors. However, I have no idea what model it is. Do you have any suggestions?

Looks nice but does it really miss a 2.0V setting?

Not necessarily. This motherboard looks like the ARISTO AM-954 model, and in that case we have the following settings....

I remembered seeing that card, also because I should have one too: it's a SuperGrace, follow the link on The Retro Web:

Yes, it's the SuperGrace/Aristo AM-954. Thank you! I bought it for 5€, but from what I can see, it has one flaw - a damaged keyboard port. I will probably have to repair it before starting it up.

That should be the PcPartner 35-8878 actually - it's the same as the 35-8954 pretty much except for the square footprint for the onboard sound that's not populated. That's a really cool baby-AT board, I got one and plan to make a small size case for it like this wonderful thing: Miniature SS7 K6-2 + Voodoo Banshee PC

Also, I bought another Advantech PCA-6751 board, this time a very late produced one since it was pretty cheap - seems to have been made in 2005-ish which is rather late for a Pentium MMX 😀 The Intel NIC certainly got smaller.
And I wanted to find out if some graphical troubles I was having are specific to my old-style PCA-6751 that was rescued from scrap:

Need to build up another one of these mini SBC cases for it although I don't really have enough ISA ports left to do that

That weird baby AT Slot 1 motherboard I bought a while ago arrived and it works!

I'm used to worrying about fans clearing DIMMs on Slot 1 mobos but.. not usually with the GPU. Gotta wonder why the practice of putting DIMM sockets immediately below the AGP slot never caught on.

And.. now that I have it, I see just how limited the LX chipset is. Never used one before so I was a bit surprised - looks like the Celeron 333 that came with the board is about as good as I can do. Still pretty cool for a board that can be put in the same case as a 386 though!

Don't mix EDO memory with SDRAM memory. You could end up sending 5V to the SDRAM modules and may kill them inadvertently. Super Socket 7 is the exception, but on Intel chipset motherboards it's not advisable to do so. You may also end up with timing problems between the two if the motherboard can't slow down the SDRAM modules to match the EDO modules.

I also bought an AT slot 1 recently. Was surprised that slot 1 boards existed in this form factor.

Unfortunately the board was not working. The seller gave me my money back and I kept the broken board. Maybe one day I could repair it.

On my new items, I received yesterday this sweet Tseng Labs ET6100. Lucky to find it super cheap. It works perfectly.
It will go directly in my late DOS/W95 system.

Wow, what a goofy card! It is probably from no earlier than 1997/1998, and yet it has those really old school through-hole tantalums like it's from the 80s. Plus it definitely has some extra holes in the backplate. I like the flat green and flat yellow color scheme though. Nice find! 😀

EDIT: Also, you probably already know this, but since it has two MD909 chips, it has 2.5MB of memory. If they were MD908, it would be 2MB. Four chips is always limited to 4MB though I'm pretty sure. Even if you have enough MD909 chips to get 4.5MB or 5MB.

With a slocket you can probably go up to 533MHz.

Mentioned in another thread I had a 478 to 423 interposer and today I found a second one in new condition, really only wanted this one as it comes with the original mounting bracket for it.

Might end up using this one and keeping the other one as the spare, might be also worth looking into if they can be reverse engineered, though im not sure just how many would want one.

Found this kit today at the flea market

Asus P/I-P55T2P4 rev 3.0, P233 MMX + cooler, 2x32 MB EDO RAM, 512 KB cache module and an S3 Trio64 DX PCI.

Everything works just great except the S3, so I'm pretty happy 😀

that's excellent, all the power of that 233mmx with the EDO ram, very nice basis for a 90's set up

Hi guys,

I accidentally stumbled upon this page and it awoke my, what I thought would be long time dead passion to socket 370 platform. That resulted in spending some $$$ on ebay and ordering:
Asus TUSL2-C motherboard
1.4 GHZ Tualatin Pentium III-S CPU
512 PC133 SDRAM (although if I remember correctly the board does not take it in one stick and you need 2*256mB)
Radeon 9800 PRO 256MB GPU

Since I am based in Europe and most parts are coming from US & China this is gonna take a while. Now I just need some PSU and a cooler to start this build but the goal is to play around with some overclocking like I used to do when I was a kid with the exact same platform 😀
