Anyway, I have always remembered that this system was equipped with dual Socket 370 Celeron Mendocino processors, but it JUST hit me like five minutes ago that this is actually really unusual, and I have not come across any boards like that in the 10+ years I have been buying old hardware.

I googled it and found this wikipedia article about the Abit BP6 and, sure enough, this was a really unique setup and the Celeron was never intended for SMP. I don't know if that's the board he had or if it was something different, but... man. I think I still have the processors, but I had basically no room to keep anything at that point in my life so I definitely didn't keep that computer around for long. I have no idea where it ended up exactly.

Add that board to the list of neat stuff that I should have held onto...

Yeah there was a bit of a fad in overclocker/enthusiast circles for the dual celeron setups in late 90s into 00. Intel didn't fully cripple the mendocinos SMP capability, but it needed either a socket mod and BIOS hack to get the cellys on a dual PII/PIII board, or slotket with dual capability, or the very rare boards that did it plug and play, but I think it invited sanctions from Intel so not many were around. This is an area of interest that suffers from loss of contemporary knowledge because forum posts were on server side scripts, generated on the fly and all old posts were lost when sites went to vBulletin etc and archive.org didn't effectively scrape them. We should have a name for that, turn of century perlpocalypse or something. You still find some mentions on the earliest preserved pages of ocforums, hardocp forums etc, there might be something in the overclockers article section about it or on tomshardware archives.

Then after 00 when single CPU ghz got real, users had probably powerleaped, LinLin-ed or used other adapters to get dual Tualatin on the boards, Pentium only, Intel had SMP properly crippled on celerons from coppermine.

However, the AMD camp had a go around with the cheap dually, when the Duron Morgan core launched and dual socket A boards could run them, so a renaissance of that type of giantkiller with dual cheap CPU came back with 1 to 1.3 Ghz Durons. (Think there might have been a bridge mod needed on the Duron)

Edit: I think the duallys weren't terribly useful to anyone other than NT or Linux wonks, or those with real workloads, until Win2k came along and made it more half consumer-y and halflife/UT etc ran on it.

Unicorn herding operations are proceeding, but all the totes of hens teeth and barrels of rocking horse poop give them plenty of hiding spots.

While inspecting solder joints on the rear ports, I noticed that the joints for the audio in/out looked like they had been previously reflowed. Not only that, but the ground pin for the left output seemed like it had a broken solder joint. It was moving as I flexed the port.

The SC-88 I obtained a couple years ago also had a cracked solder joint for one of the output RCA jacks. I did not see any previous repair evidence, and thankfully the pads were intact, so it was an easy repair.

I chose to tear down my Pentium system since it's kind of become redundant now that I have a good, working 486 build. In turn, I set back up the P3/1000 board, and threw my Voodoo2 in there. I do wonder if the noctua fan in the front is enough airflow, though. I can definitely feel the air from the fan near the voodoo, but I do have a dual fan solution if I need to cool it more.

Lunch break.. figured out how to even do software fan control on a 9600Pro - is this a first? Dunno, but it's a nice and fun mod.

Spending some time with a GeForce 2 MX in one of my Power Macs and I've been severely underestimating the 2 MX this entire time, it seems. RTCW at 35-ish fps 1024x768 or 65-ish at 640x480 (at 85 hz on a CRT, maxed settings) is way smoother and nicer looking for those framerates than I'd ever expected, for some reason I was expecting something closer to the Nintendo 64. And that's in Tiger, I have yet to run the game in Jaguar or 9.

Didn't people also play this game on Windows PCs with that same GPU back in the day?

GeForce2MX 400 on Windows is roughly the same perf as a GeForce256
GeForce4MX 440 can overtake a GeForce2 Ultra.

Graphics were moving very fast back then. The low end could overtake the high end in just 2 years.

Anyways today in my retro activities.... spent like an hour removing a soldered coin cell battery in a Compaq Deskpro 2000 and installing a CR2032 holder. Which didn't work.

Then I saw the header labeled "External Battery"......

Morale of the story always look for easier routes before taking the hardest one.

it was probably not soldered but point welded. This is common in many compaq machines of that era and a real nuisance. The best way is usually to desolder the whole coinholder from the board.

I'm getting around to tinkering with some boards I got recently, but both have this same style of CMOS holder. What is the correct way to remove the battery? Yes, I've been burnt before...I blame the flimsy old metal.

Plastic spudger under one edge to live the edge of the battery up above the edge of the holder and then slide it out sideways.

Not done a lot of vontage computing the last couple of years, but finally got time to fix up this DX2-80 VLB system.
Then I put it up for sale locally, as I have more hardware and machines than I can use.

Feels like building a mod-chip for a graphics card. WIP - more to come. Layout done.. some small tweaks necessary. PCB width is too large as well.

Some nice addition for R300 based graphics cards.

Following the other thread I'd guess this has something to do with measureing the temperature sensor on those cards.
But I won't ask more questions and just let me be surprised 😉

If I'm right I'd have some 9800 cards to take advantage, if it's applicable for them too.

Diagnosed a faulty Diamond Viper V550 TNT AGP graphics card.

The attachment Diamond Viper V550 AGP no video.jpg is no longer available

The card is successfully detected by the PC, but fails to display any video output.

After some physical inspection I discovered it's missing an inductor (L16) and several capacitors (C255, C256, C257). There was also some abrasion on nearby resistors, so this card likely physically hit something to knock these components off.

Not sure if this is the reason it won't output video, but it's a starting point. I plan to remove these components from a working card so I can measure them and then order some replacements.

If everything works out, this will work with either R300, R350 or R360. Next week will give some progress on this.

For testing, you can bridge L16 with a short piece of wire or a 0 Ohms resistor. It is a filter inductor for incoming power, without it in place, the GPU is likely missing a voltage. That can definitely explain why the card isn't showing an image.

BTW: If anybody has a legit DEAD 9800XT - give me a message.. by dead I mean really dead. I need the PCB for science. They're just hard to get.. OR a high res photo of the GPU area without cooler. Much appreciated.

I might be able to help with photos sometime next week. I have one that I will need to replace thermal pads and paste on.

You might be in luck. I have a dead one without the GPU, but I don't remember if it's the XT or not.

Yeah, it is a nice machine. I had it fully taken apart, and did a rebuild. Put it up for sale on a local online trade thingy. But will not say wich nor write the price, as it is against rules here.

VLB controller with own BIOS. S3-805 VLB gfx card, 16mb RAM and around some 500mb old school spinning HDD. Installed with MS Dos and lots of nice stuff.

Broke out the old GeForce 2 MX, man I loved this card back in the day, I could proudly say I had a GeForce 2 and quietly whisper the MX part. These were such great cards for the money
