Not yet bought but looking at picking up this unusual CPU from eBay.

“ST486DX2-66”

A 486 that isn’t Intel or AMD, I’ve never seen one but assume shares socket compatibility.

It's basically a Cyrix. As they were fabless a bunch of "foundries" made them, here it's SGS Thomson (now STMicroelectronics). They ere not so uncommon but a bit odd yes. You also find the same chips with Texas Instruments and IBM markings.

I bought 2 graphic cards for 30€ including shipping, an ATI Mach 64 VT ans a Radeon 7500 (die-shrink of the original Radeon). The package I got today is a bit of a good surprise...the 7500 actually is a 9700! Not what I ordered, but I'm perfectly ok with that this time. Do these 9700 overheat and kill themselves or is it ok running it with this stock cooler/fan combo?

A few dings on the capacitors of that red card whatever it turns out to be. Something I keep wondering about Radeons of this age plus or minus a couple of years, the capacitor cans seem to be made of dollar store tinfoil, not even the good Reynolds Wrap, and dent extremely easily, so how much of a ding can they take and still work? I have an 8500 with some dinged just a touch worse than that and it's not working, so dunno if I should ignore them and troubleshoot other stuff or change them first.

Thanks, I really appreciate that. Doesn’t sound like a collector’s item but I might pick it up to compare with the Intel version.

Don't get me wrong, these days they are not common anymore, as Cyrix are not common anymore. So it's still a collectors item at this point.

What makes something a collector's item is not down to just its monetary value, so much as whether a collector wants it. In the CPU-World forums, you'll find a lot of collectors who include this and similar in their collections. It's not valuable, but it is collectible.

The heatsink is good enough for the 9700, the issue is the metal shim to protect the die that surround the chip is a little bit higher than the gpu itself which then cause the gpu to overheat and gone.

Not every R9700 had that shim issue. For example I had one back in the day with shim with exactly same height as the core.

I just recently got 9800pro AIW which I posted here and I popped the cooler off today and here too, shim and core are exactly the same height. Funnily, there is a small rise on the cooler bottom where the core contacts the cooler. It is very small, like 0,1-0,2mm or something like that, but it is there. But when I checked the shim and core with a metal ruler, no light could be seen between the ruler and core.

Can confirm your claim - my 9700 Pro from Hercules has the shim at the right level - no light shines thru.
I'll admit though, I had to use a Deepcool V50 cooler on mine as the original had broken blades.

Same couldn't be said about my 9800SE AIW unfortunately. That one came with artefacts and I could see light thru.

This lot ended up tempting me, so I am now awaiting their arrival... was just idly pondering needing another PCI soundcard or two... and this popped up..

In order, Audigy SB0090, Live CT4780, Live CT4780 , ewaste*, NIC, NIC, RadeonVE DVI, Radeon 2400Pro PCI 32bit.

*ewaste is one of those extra monitor connectors for onboard graphics, don't think I'll have a use for it, unless someone tells me headless GPU can be used with them.

I dunno why but I'm also a sucker for late PCI graphics, and I wanted some lower profile NICs to be using next to things that need to breathe too.

Ah, it's in Purolator's hands now....

I am a bit wrong about that RadeonVE maybe, not a DVI port but one of those ones that needs a splitter cable... I have one I am hoping will work... well choice of 3. I am unsure yet whether this will find a home in a low profile compaq p4 willy desktop I have or not. I think it's got a TnT2 m64 in it at present. I have also a MX440 equivalent low pro quadro. Given the Radeon drivers got updated in the early noughts such that it's more DX7.5 ... i.e. extra features are enabled under DX8 but it's not full DX8... I am wondering if it is superior to the MX4x0 class... but the MX might rev higher... though be more complex to take back to 98 given it's the quadro version... hmmm. Willamette platform and pre dx9 graphics will push deep into XP era like a musket ball pushes into Sherman tank armor though, so maybe 98 optimisation is better.

*ewaste* apparently supports that intel thing for spreading the glory of GMA950 graphics across multiple screens. yay

Sorry to hear, getting harder to find. It’s weird that I see your post today as I just received a 5150 p/s I was searching for a long time. My system is a Rev.A 16-64k with an upgraded p/s. Finally , I now have the original black 63w to install.
Fortunately, no shipping damage.
😀

That is a coincidence as mine was a black 63W unit too.

Received this today... like the old days: three generations living in one house. I know gramps' [direct] memory [access] isn't what it used to be, but it's interesting.

MU2000 from Japan. I can't find a voltage transformer for the 100V so I'm just gonna buy another 12V 2A psu.

Honestly a better bet anyway even if the OG PSU was universal. A brand new PSU will be smaller, lighter, quieter, more energy efficient and less likely to blow up on you. Same reason I didn't try to get original PSU's for my MU-50 or UA-100.

Also, very cool! Do you have SmartMedia cards for it?

Speaking of my MU-50, that's one in your mountain right? With a 32, 55 and an 88VL?

Gonna keep both the MU's, or swap out the older one?

I have this board or a similar one. There is no DMA support on the ISA bus, if I remember correctly. It's still useful for Adlib OPL though.

Via C3 'Samuel' 500MHz CPU arrived today. Still planning on an Ezra but picked this up cheap to experiment with SetMul and emulating low-end hardware for DOS games.

Damn this thing is already sloowwwwww at stock. A full thread to follow, but it benches like a Pentium II 233 at stock, or worse!

That is a neat coincidence! Wondering, on yours does the fan intake at the top have the securing nuts recessed in the top plate or is the top plate flat with the nuts raised? The one I got is recessed but the “holy grail” earliest design used a flat top plate.

I am once again trying to 486. And this time it's at a whopping 100MHz. I do also have my DX-50 and DX2-66 to toss at it if need be for speed.

But it's got something nice in it. What is it?

Oh hey, a SB Pro 2. and what's that attached to the end of it?

A matching CD drive. I don't even know where to start for getting said CD drive to work as I have never done a proprietary drive on a sound card before. But hey, I can't complain too much. I was even able to properly test out my 5151 since it doesn't hang like my pentium machine did while booting.

I think I remember someone getting into how pentium CPU were too fast for the ROM or RAM on the original mono and hercules cards, but the single chip solution winbond, sarc etc cards that came along later usually worked.

I bough one of my Unicorn Motherboards today, a Epox EP-MVP3G5 Super 7 motherboard with a full fat 2Mb of L2 Cache . The board has been tested by the seller who is a retro collector themselves with some rather rare parts and I have bought parts from them before.

Been hunting for this board for a number of years now and this is the first I have seen for sale, I think it deserves to be paired up with a modded K6-2+ 570 to K6-3+ 600 I have and possibly a Voodoo4 4500 or 5500. (I might throw a non modded K6-2+ 570 in there at 600 and see which one performs better with the 2Mb L2)

About the only blemish I see is some socket discolouration, seller says its likely from Ozone being produced by the nearby VRM coil components browning the socket plastic and doesn't affect the board at all, I have no reason to doubt this as it seems plausible.

Such a lovely rare board.

You lucky bugger. I didn’t see this on eBay today. Where did you find this beauty?

Edit: Ok found the listing it’s international. It’s super rare so worth the price.

I have it saved as a saved search and its never popped once in the five years Ive had it saved and then bam it pops at 3am from a seller I have bought other rare parts from out of Germany (Seller is a great Guy). I didn't even care what the price was and just bought it honestly the Voodoo5 cost me more than this board did.

Totally worth it to have this board, not often you ever see 2Mb of L2 on a Super 7, should have good AGP compatibility too so it may even run the ATI Fury MAXX *yeah not likely that GPU only likes a handful of boards
