If you typed all of that out, bravo! 😁

No way, I just asked ChatGPT to give me an equation that made 800 + 50 look like a 50% increase. 🤣

🤣 and people are scared of AI...

850 / 1.5 = 566.666666...

🤣

I don't want to keep going with the OT posts, but, just to add one more data point to this: I once asked Chat GPT to tell me for details of how to do some very specific and unsafe thing with a power tool, just to see how dangerous the advice would be and it said something about using a steady pace. No mention of "You probably don't want to do that..." 🤣

Fun times.

Anyway...

To get back on topic, I recently picked up an Asus P5A-B motherboard with a little bit of minor damage and a K6-III 400 installed in it! Crazy... I haven't been able to get a decent deal on a K6-2+ or K6-III in all the years I've been doing this, and now I've managed to get a good deal on two of them (in nice motherboards!) in less than a month.

This wasn't exactly cheap, but it was still way better than eBay prices and I couldn't pass it up.

This was all the extra stuff that came along with the good stuff. 😀 Should be useful to have some IDE and SCSI adapters, but not what I'm really excited about.

This is my first VLB card. Unfortunately I don't have a board with VLB slots yet... Something to look forward too anyway.

12MB version of the Voodoo 2. Not quite a visual match for my Creative V2, but I don't care that much. Just really happy to be able to mess with SLI now. And I'm really happy that drivers exist to allow SLI between different vendor cards. I made up an SLI cable from an old floppy cable and I was surprised how quick and easy it was. Now I need to agonize about what sort of system I would want it in. 😀

And finally, the really big deal. I had one back in the day, but it's long gone now. Based on the average prices I had just been resigned to the idea that I'd never have one again. I'm kinda buzzing with how excited I am to have one back in my possession. 😁 I suppose the only downside is that I'm pretty sure I'll need to do a lot of research to avoid the pitfalls with this thing. But that's kinda part of the fun.

Offered and bought a used Automatic Seiko from USA because I had to replace my current Seiko automatic watch had incorrectly serviced using thin crystal (sapphire I think) finally shattered, should had been a thicker type but the crystals I see out there even correct one are heavily beveled than originals. Repair watch forums had same comments about these issue.

This watch is much treasured because this is hard to find this particular dial style but I fortunately found another with same face style. Easy to read even in the dark.

I'll rehouse my other watch in another case with good crystal once I found another one. Seiko is smart about keeping movements the same dimensions, eg: I can swap ancient 1960 era 17 jewel 6308 movement for new modern Seiko Sii 24 jewel NH35A movement and keep original hands and dial.

BTW the india sourced seikos are 100% fakes (including case) even the movements are sloppily serviced or worn out, even rusted (!!), I did source an couple for curiosity sake. Not of correct dimensions vs original Seiko design.

Cheers,

Just arrived, a Sound Blaster X-Fi Elite Pro, bought it to finish off my high end 2006 mid-range XP build.

At most I'd expect about 6% increase. ((850/800) - 1) x 100. Basic math.

I don't know...

x = (800 + 50) / 100

Next, let's define a function f(t) as:

f(t) = (t + 1) * (t^2 + 1) * (t^4 + 1) * (t^8 + 1) * (t^16 + 1) * (t^32 + 1) * (t^64 + 1) * (t^128 + 1) * (t^256 + 1)

Now, let's evaluate f(x) and subtract 1:

f(x) - 1 = ((800 + 50) / 100 + 1) * (((800 + 50) / 100)^2 + 1) * (((800 + 50) / 100)^4 + 1) * (((800 + 50) / 100)^8 + 1) * (((800 + 50) / 100)^16 + 1) * (((800 + 50) / 100)^32 + 1) * (((800 + 50) / 100)^64 + 1) * (((800 + 50) / 100)^128 + 1) * (((800 + 50) / 100)^256 + 1) - 1

Now, let's simplify this expression by multiplying out the terms:

f(x) - 1 = ((850 / 100) * ((850 / 100)^2 + 1) * ((850 / 100)^4 + 1) * ((850 / 100)^8 + 1) * ((850 / 100)^16 + 1) * ((850 / 100)^32 + 1) * ((850 / 100)^64 + 1) * ((850 / 100)^128 + 1) * ((850 / 100)^256 + 1)) - 1

Simplifying further, we get:

f(x) - 1 = (850 / 100) * (850^2 / 10000 + 1) * (850^4 / 100000000 + 1) * (850^8 / 100000000000000 + 1) * (850^16 / 100000000000000000000 + 1) * (850^32 / 100000000000000000000000000000 + 1) * (850^64 / 100000000000000000000000000000000000000000000 + 1) * (850^128 / 100000000000000000000000000000000000000000000000000000000000000000 + 1) * (850^256 / 1000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 + 1) - 1

If we evaluate this expression, we get:

f(x) - 1 = 4.5 * 10^30

Now, let's calculate the percentage increase of f(x) - 1 over f(0) - 1:

((f(x) - 1) / (f(0) - 1)) * 100% = ((4.5 * 10^30) / 1) * 100% = 4.5 * 10^32%

Therefore, we can say that 800 + 50 is a 50% increase over... something.

Basic math.

What's the mathematical background of this?

After a long time I got another CRT - 19" with an ok to good picture for 20 "bucks".
On monday I'll grab another one.

It's good to see one more CRT being rescued 😀
Since you wrote 'another' I'd like to hear your opinion on my question in an older post
"[...] I just don't have the space to collect them all [...] How do you guys solve this problem? Do you grab everything or only the 'better' ones?"

Bought this Terratec 5,25" unit but no sound card, Intel 686 CPU and an Nvidia TNT AGP VGA card.

surely you mean IBM & Cyrix.

Yes. Sorry. Wasn't paying enough attention when writing the post.

Did a best offer on ebay and got this real cheap. The final part for my athlonXP build. Probably..

At last, the DDR version came by.
Asus V6800 / GeForce256 with 32MB.

Rescued an old computer from e-waste that looked somewhat uncommon. It's a Digital Prioris XL Server 5133DP. I haven't found much info on the web about exactly this model, but back then (around 1996) it must have cost a fortune. It has VGA and SCSI onboard, 5 EISA slots, 3 PCI, two CPUs on a plugged-in CPU module and all RAM slots are occupied. Unfortunately the front door is missing but the tower is built (and heavy) like a tank. I hope it still works. Haven't tested it out, yet..
Here's a website with photos from a similar model.

I got the 64Mb version of that card recently, the DDR model does seem to be pretty rare.

I had a 64MB DDR model of this exact card a few years ago. It worked briefly, then displayed artifacts once and then never worked again. I replaced all the caps and it was still dead. I ended up selling it in a big parts lot. Now, I'm wondering if it was just a bad BIOS or something. 😮

It was missing the backplate anyway, so it was still going to be a project even if I ever got it working... but... I so wanted that thing to be functional.

Sounds like a bad memory chip to me.

Today I got this 80GB Samsung SpinPoint P80 SP0822N IDE ATA/100 7200RPM 2MB cache hard drive. Any opinions?

32GB pin setting is very useful for older builds. Good stuff.

it's full of possibilities for restoration and new projects though, an interesting find

i have a radeon 9250 in an athlon xp, a nice card for what is often a very good price, it can play most games of that time just fine
