Nothing special, only 17 Celeron 300A CPUs, they are common, but I love the way they work at 450MHz 😀

The 366 mendocino is the sweet spot for me, most of them do 550 run at 100FSB. Much above that you start having to screw with volts and special tuning. Though 124 is a common bus speed step that one might get 300As rocking on. (For the ppl who don't know, single mhz bus speed steps didn't get to be a thing until very late 90s, and still weren't common until into 2000s. Instead you had like 60,66,75,83,95,100,105, 112, 124,133... maybe available in BIOS with a "soft cpu" setup, but more likely switches or jumpers on the board and half the in between ones were undocumented)

Slot or socket? Slot 1 seems to be common (on eBay, if that's an accurate measure of reality) but all the Socket 370 ones seem to be concentrated in Eastern Europe (again, on eBay).

All Celerons are Socket 370, from old Cisco PIX firewalls.

We live in a fully disposable society. We're the outliers who try to fix our broken stuff instead of just tossing it in the trash can.

I'm wondering: will our collection end up in the trash can after we die? I'd like to think it won't.

I'm going to instruct my wife and/or son to list my stuff on eBay after I go. There's very easily at least a few grand worth of stuff (at this time) in there.

You'd be lucky to get a 300A running at 124 MHz FSB. Back in the day, 112 was even not common. Unless, of course s370's were better/later steppings. I don't remember s370 even being a thing when 300A was the shizzle 🤣

I still keep my first Slot 1 Celeron 300A. Of course, the first thing was to try it at 100MHz FSB, but it was unstable because of the poor stock cooler. The year was 1998, no aftermarket coolers in Bulgaria, time for DIY 😀
Still works stable at 100MHz FSB, but has a bit steampunk look:

It was quite a little journey, and I might give it a thread at some point. There is one on OCAU: https://forums.overclockers.com.au/threads/th … treets.1299937/

this is simply fantastic! that thread records a great journey. It truly is a top rescue job, a pleasure to see 😀

Well, LOTS of 300A's ran 450 with stock cooling back in the day ..

Hmm, might just buy a cheap PIX 506E then. I'll add that to my sprawling list of bookmarked eBay searches 😁

NOS Intel (and some Mitsubishi) 27C128 and 27C256 EPROMs that was in the scrap bin.. saved 'em. Already UV erased and programmed 1 of the 27C256 chips and it worked great. (for my Pi1541+EPYX FastLoader)

4. When the truck came to load old HW I grab from it nice looking Dell GX1

They're nice looking systems, I have 1 myself, but the thing that really irks me about them - the lack of AGP. If they had an AGP slot, they'd be a killer classic 440BX-based PIII gaming system.

Scored this working AWE 64 gold.

Its a bit rusty on the metal plate and connectors:

Do you have any idea how can I clean it easily?

For the metal bracket you can use CLR and a fine steel wool and for the connectors you can use the CLR on a soft cloth. I've done that quite a few times and everything comes out great.

Citric acid. Dissolve some in hot water, put the bracket in. Observe how the rust disappear (spots where it was will be darker than the rest of the bracket but still it's better than rusty spots).

Citric acid is much better to clean battery leaks as well - cleans much better and faster than white vinegar and doesn't smell.

K7T Turbo - too late to recap? Excellent condition minus the caps...

Yeah, but it doesn't remind you of fish and chips, so that's a negative to using citric acid over vinegar 😉

Looks like a bit of dust around the CPU socket that would be good to clean up. It's probably down draft from cooling fan. Can't see any obvious corrosion so you might be ok. Looks in better condition that a Slot A I recapped years ago.

On the other hand, lemon drizzle cake.

You guys are overcomplicating this rust thing.

Use a damn wire brush and be done with it.

All this talk about lemons makes me want to bake a lemon cheesecake...
