extra lucky today, found a whole socket 5 pentium 60/66 system, haven't powered it on yet.

very surprised the cpu doesn't have any paste on it

Up until Pentium 3 (ZIF CPUs wise) you didn't need thermal paste. Starting with the PGA370 Pentium 3 CPUs it was needed.

I love hgow they didn't even remove the sticker off the top of the CPU... Yay! Let's make sure there is an artificial air-gap in between most of the CPU and the heatsink.

I never knew that, most of the cpus I bought 486 - early pentium all came with some kind of paste always. Always learn something new on vogons!

haha yeha it works out well for me because that cpu is going straight into my cpu collection, looks spotless!

And im going to be putting a 486 vlb with amd 133 which parts I have been accumulating and was short of a case!

Just identified the board its a soyo SY-032 with a isa vibra 16, isa floppy controller and pci hdd controller! 2x creative cdrom

This is one of my best finds to date!

going to fire it up once and check it out before putting in the 486

I used thermal paste back in the 486 era.

Honestly it's a YMMV situation. At least I didn't need thermal paste on ceramic CPUs. Only the exposed core (PGA370 Coppermine and usually all Socket A CPUs) and the ones with IHS (late P3 and all P4 chips onwards) I needed to apply thermal paste.

...would imply it is indeed socket 4 and the typo "socket 5" being a typo in the original post. That is indeed a very nice find...

That's a bit unusual... which card is it? Also, what video card?

dersammler is correct, I fired it up and P75-S
Also writing says socket 5, I must of got the board identification wrong but it looks exactly the same as the one in the link on the picture, perhaps it's a slightly different revision.

Here is pictures of video + pci hdd controller and socket
These are all very nice parts for my collection!

Turns out has windows95 installed and 500mb hard drive too and works! I opened up the psu was quiet clean too and no visual leaks swelling on capacitors!

Quiet nice system but my plans are to put in a 486 vlb with a 586 133 clocked to 160 in this case which ironically is kind of comparable to P75 or P90 clocked to 160

I found the correct motherboard it is SY-033 A2/A5/A1M

^Oh, well... socket 5 is nice, too. TIM was even less necessary for these as they run much cooler than the socket 4 P60/66 chips did.

There is little information about that video card but there is likely a S3 Vision864 or Vision868 under that sticker, given the date and presence of SDAC.

PCI IDE card looks like it's CMD640B based; be warned of the data corruption bug that can affect these controllers.

yes it said S3 Vision864 on start-up
thanx for the warning ill be sure to try not use the pci controller, all the pci boards I have built in hdd and floppy controllers, but good to know for future projects

It does not make sense to have a heatsink or cooler on top of the CPU while having no thermal compound... 😉

it is a common sense in electronics to HAVE a SOMETHING between the hot surface AND heatsink. WIthout thermal paste/pad/compound it will be in a very bad thermal contact and inefficient usage of the cooler.

Without thermal compount with hot CPUs of course it would mean the overheating, while for cooler CPUs it will be as a result that the fan is not needed on a heatsink when thermal paste is applied.

yeah I put heat paste on everything with a heatsink it never hurts.

Also the way I like to see it, on microscopic levels no surfaces are totally flat so the paste helps to fit those gaps on heatsink and cpu, everything touching

Well, many computer builders did so back in the days, it wasn't a big deal. Sure it's better, but it wasn't really a requirement.

That's not correct. The gold cap is a heatsink already. Thermal paste is only to prevent the incurrence of hot spots or to link uneven surfaces. It's completely unnecessary to use thermal paste with CPUs that have a gold cap or any other form of a fixed heatsink attached already. And it wasn't done back then because of this.

The first CPUs that *required* thermal paste were those with the die directly exposed.

Got to do some dumpster diving after another lab was cleared out at work:

full.jpg

A huge power block, some KVM octopus cables, a few copper (RJ45) SFP modules (which I need for troubleshooting why my optics at home aren't working als I'd like), some antistatic bags, a Cherry MY-1800 compact keyboard and a 19" complete PS/2 / VGA KVM solution with TFT monitor and laptop-style (but mechanical laptop style!) keyboard.

Had been wanting to try out MY-switches, but given their not too stellar reputation I didn't really want to spend any money on them. Problem solved. Of course, a colleague who was in the office earlier today picked the real cherry out of the pie - some Swiss-made custom keyboard with what felt like Cherry MX blue switches, but possibly something more exotic, as the click sound seemed softer and the tactile feedback more definite than I'd expect with MX blues. Couldn't convince him to part with it, unsurprisingly.

I was dumpster diving a few days ago. Got these ISA cards. Anyone knows what were they for?

Battery backed RAM is what they look like to me.

Possibly for some nice RAM drives on an old system.

Heck of a lot of batteries for 1 card (3x NiCd and 1 Lithium).
