Another success today was joining the "Tualatin + BX" club - ABIT BX133-RAID and a Tualeron 1.3GHz.

Did the pinmods as per this modding guide, got it to work properly and didn't need more to do to the CPU:

- removed AN3,AJ3, AK4
- made a wire wrap around AK26 and then soldered the other end to where AK4 pin once was
- ???
- p r o f i t

The bridge between AK36 and AM34 wasn't needed - I measured for continuity between AK36 and any given GND point on the mobo and found out it's grounded. YMMV though, depending on the mobo used.

Sweet! That method looks pretty tricky. I did it by way of getting an interposer from that guy who sells them on ebay. I went for extra silliness by running it in a slocket on a (baby at) slot 1 board. 👌

Did some cross referencing and assert with evidence that RetroWeb needs correcting.

Got some progress done.. first time letting the khan-monitor use the integrated i2c bus of the R300 - directly from the extension header.

Everest shows the first signs of life:

Under load:

Guess that's the worlds first 9500 Pro with hardware monitoring? (aside from the tyans)
More to come, but this already looks promising.

More testing of the Tualeron 1300 on the BX. It even runs stable at 1733MHz w/ GF4 Ti4200 and 384MB RAM.

No korean PCB - just three pins removed and a bridge. May do a full blown Tualatin if I have the chance to score a few 1.4s.

They start at 133, only i815 will let you go up to 166 P-III Tualatin 1.4GHz overclocking

Technically around 142-ish is where it stops POST-ing with the 256k Tualeron 1300 - that's roughly around the 1.8GHz mark (which for a BX is a fairly HUGE number in my opinion - not that 1733 @ 133FSB wouldn't be, either!).

The 815EP based ST6 might well be able to take it past 166 I believe - my 1133 runs at 1.6GHz (188FSB) with no issues on ABIT's ST6. It's so far the only board I have successfully seen to do past 166 with ease out of all I've owned - TUSL2 doesn't seem to go past 166, and MSI's 815EPT Pro-R is apparently BIOS hardcoded to 166 max.

I previously thought this was the only photo that "shows" my old family PC, which I've been on a years long quest to identify.

But I had a feeling there was one big piece of evidence left. Went back through the photos today, and only noticed this in an index because I had a flashlight on it. Can't find the actual photo - looked through every single pack of photos for the negative at least, and it WAS in the very last pack with a completely unrelated set of photos.

I will get the negative digitised but not too much hope tbh. I can make out the index photo slightly better in person but it's a fumbled photo with poor lighting. Hopefully when blown up it'll show at least enough detail to make out if it's the model I think it is.

My understanding is that we don't actually forget anything. Instead, what happens is certain memories become hard to access due to bandwidth limitations.

And, we don't index or recall our memories in chronological order. Instead, we recall them by associations (smells, motions, emotions, temperature, heart rate, etc.)

So if you model how you completely felt when you were fixing your PC, and relive that complete set of associations, it's possible you might recall technical specifications you once knew.

But beware - when you recall memories, you also write new memories of recalling memories (recursion) and so un-recalled detail can be buried even further! Given that sensitivity, you might not benefit from a half-arsed practice run.

This is, imho, the entire thesis of therapy in a single post because if you think about it.. a person is the sum of their memories, and the way a person experiences anything is really just an effect of how they remember experiencing something else..

What's wrong with it?
It's both facts and hilarity.

To memorize and revise I used the loci technique and many buildings in my town are still this or that rather than being just buildings 😀
Some colors are the ones I used to makes links and underline concepts.

Most of us have this path well trodden in their memories 😀

This weekend I fought with my Gateway 400, AMD K6-2 system with ALi chipset and integrated AGP graphics... Bought a PCI 9250 card for the system to upgrade the video and couldn't get it to work. Love old tech! It would should stuff on screen for post and then nothing, would go to no signal. I could reset it multiple times and then I could get into 98, install drivers, restart and then would be right back to restarting multiple times before it would work again, so I just gave up. Tried the card in two other systems and it worked no problem.

I also took and played around with my P4 system from 2003 with the original install on it and a bunch of games. Downloading CD images from The Internet Archive and seeing which ones I want to get the physical copy of to add to my collection. One, like Homeworld 2, would install just fine (tried on another system), but then wouldn't start so had to find a nocd for it, and now it is added to my list of games to buy.

Games I want to buy are: The Sims Medieval (I have, but it was used so can't play it because the serial is in use), Worms Armageddo, Need for Speed II SE/Most Wanted Black Edition/Carbon/Undercover/ProStreet, Sacred 2, Aquanox 2, Midnight Club 2, Sid Meier's Sim Golf/Pirates!, CivCity Rome, Tropico 1/3/4, Midtown Madness 2, Homeworld 2, and a couple others that I forgot to write down.

I don't trust my memories tbh. In the lifetime of that PC I was 6-12, and all I knew about PCs was that they had the Pentiums - Pentium this, Pentium that. In fact I remember telling people I had a Pentium II, but a printed Windows resource summary report I found a couple years ago indicates it was actually just a Pentium (MMX). So why was I so sure it was a PII?

I only think I know what PC it was because of that report, thanks to the BIOS revision and date listed. And some elements of the design do ring a bell, while some others kinda don't. So could be a red herring. I just need enough detail from that potato photo after processing the negative to tell if it's this specific AST Bravo LC/MS 51xx/52xx series chassis design. If it's not, then RIP.

Speaking of memories, I've been trying to restore an old Windows 98 box: a Soyo SY-6BA+ III-2AA2 motherboard with a celeron 300a. It's also running DOS 5. Don't ask me why it's got to be DOS 5, I don't quite remember, but it has to do with ... memory. 😀

So I'm thinking... the more I play with this... the more bloody knuckles I get... the more I remember.... Maybe there's something to that association thing.

Anyway, I decided to ditch that crappy old case, partly because I mislaid both side panels, and use a nice server type case with sliding drive bays and nice wire arrangement. and... Uh oh! The nice server case I chose has the power supply on the bottom, and the power cables don't reach. Well, that can be fixed.

So I had 7 computers, only one of which was useful (a plex video server with 8 hard drives), and now that my CDs, DVDs, Blurays, and 4k discs are all ripped, there's another 6 hard drives. That means a new case to fit at least 14 drives.

Long story short, I pulled out everything to deal with all 7 boxen in one swell foop. There's also a 2-bay Synology NAS and a Terramaster 6-drive USB DAS. The NAS is still useful for backup & synchronization. The DAS, not so much. Two PCs went to the trash: a P4 (windows 98) that I never liked, and that !$%&@*! dual athlon space heater running XP that I finally retired about 2019. All the disc drives (floppy, cd, dvd), useful cards, cases, etc were kept. It's not much, really. Just a lot to do at once without getting organized.

I note that previously, I only posted here in 2011 in the midst of my last knuckle busting adventure with a dual athlon. (And I actually bought another Tyan motherboard after that--a sucker born every day?) So, here's another major multi-computer upgrade adventure 15 years later. A lot's coming back to me--and the association with bloody knuckles might have done the trick. One big frustration is this motherboard doesn't seem to like hard drives larger than about 30 GB. And I mislaid my Promise Tx2. Fortunately, those are readily available. As is the 150 IDE + SATA. Hmmm...

The one thing I still need to research more thorougly is MIDI. My ISA Sound Blaster Awe-32 is a pain in some DOS games. And why do I only have a fancy shmancy USB joystick. Where's the old serial stick? Bwaaaahhhh!!!

I also remember how unstable this Soyo SY-6BA+ III-2AA2 motherboard always was. And is. It just doesn't post half the time, cold or on a reboot. Well, it never rebooted properly, but something something something ... I blame the power supply. 😉 Might have to crack it open and take a peek. Might be time to pull out the soldering station.

Thanks everyone for still being here after all these years. Even though I didn't post much back then, or since, but just read and learned, this place was and is just fantastic help! Wish I could offer more, but some of you... Wow! Just WOW!!!!

Spent a good amount of time playing a "new" Pac-Man for the Atari 7800 today, it just arrived. It's faithful to the arcade port version with some additional features, such as the ability to generate random mazes, making it more challenging and fun! They even got the original artist for Pac-Man on the 2600, Hiro Kimura, involved to do all the art. Pretty cool IMHO. 😀

I bought a new Atari 7800+ to go alongside my newly acquired original 2600 "heavy sixer" (Sears Tele-Games version).

Dual Athlon board, huh? Sounds neat, though probably not so much in practice.

Heya! I'm not a regular here either - my interest in retro stuffs ebbs and wanes, but I'm always thrilled a community like this exists.

For the mobo, yeah the caps are an obvious place to check, but also try reflashing the bios - that's solved many a weirdness for me in the past.

Neat, I'm also on a BX133-RAID except I went with a Tualeron since it's cheaper to find at high speeds. I'm probably dropping a GF2 Ti on it, although a 3 Ti would've been my choice initially as well, even if my Tualeron 1300 runs @ 1733MHz.
