Found this 386 motherboard.
Really tiny and compact, 5 ISA slots with 486 ( 168 pin PGA) support.
Unidentified so can someone help me recognize it?
CPU is a soldered AM 386DX-40.

Looks a lot like this one https://theretroweb.com/motherboards/s/inform … -it-am33-40-dlc
I doubt it's a 486 socket. More likely a 387 or weitek coprocessor socket

Yeah, sounds like that one.
The socket though is too large for a 3167 or 387.
It's a 145 pin with a strange shape.
Anyway, what kind of damage did this MB took?
It looks more than the leaked battery due of those strange oil-like stains.
Can i run it safely with the external BT connector?
Edit: too little pins to be a Pentium OverDrive.

It just has an extra inner square of pins. both weitek or normal copro would fit.
why those inner pins are there... maybe a manual could tell us.

An Intel DP35DP (LGA775) motherboard with CPU and RAM was going to the recycler, it's now mine. Special thanks to Intel for actively removing all BIOS for their motherboards from their website in 2019, what a dick move.

The old Pentiums, K6 and a broken Athlon XP were kindly donated a couple of days ago.

what a nice rescue that was!

Basis for new build?

Not really...I'll just keep it in a box, I have enough other systems around!

I had a closer look at the Intel board and it's really well made as you would expect. It's a very first generation "Conroe" system, the first LGA775 I actually own. The CPU is a mid/low class Pentium E2200 dual-core paired with 4GB of DDR2. I might just boot a Linux on it and run some benchmarks to see if everything is stable before stashing it away for the next 10 years 😉

Those E2x00 overclock like crazy, 100% plus. Just bang up the bus speed to the next notch and hang an at least half decent cooler on it, stock ones even, and it's not even breaking a sweat.

Intel Core2 era boards have no OC'ing options in the BIOs as Intel was trying to discourage overclocking at that time.

I'd just throw a E8400 on that board and run with it, no DX10 era games actually NEED a quad or more than 3GHZ. a 3GHZ dual core was smoking fast at the time. An E8500 or E8600 would be even better if you can find one cheap as those get you to 3.1 and 3.2GHZ respectively.

If it supports a higher bus speed it can be overclocked... https://linustechtips.com/topic/767799-how-to … th-tape/page/2/ you don't have to mess about a megahertz at a time with these, a substantial jump from stock to next bus speed works most of the time.

Eh like I said there isn't much reason to anymore, unless your just OC'ing for kicks. An E8400 won't bottleneck any period correct game.

This is for CHIPS super 386, J386xxx. Very rare CPU and looks like a 486 package in a 144 pins.

Uhm, so it means almost certainly is not going to be found easily, i take.
Anyway, another mb arrived this week.
A 386-486 hybrid motherboard, that despite the barrel battery, it miraculously has no damage or leakage.
The mainboard is perfect and the battery as written above, has a very minor leak (some blueish oxide at the negative pole of the battery) so the motherboard is in excellent condition.
The battery had a 0.09V voltage left when I measured it with the multimeter so I take that it is dead, amazingly though it didn't leak.
The motherboard has sockets for 386 and 486, VESA and what it seems a ps2 mouse connector just next to the keyboard connector.
Is the "486" socket an hybrid to house both 387 and 486s?
Can someone help me confirm this?

I stopped by my local E waste facility to drop off some junk, and I had to laugh at this sign. They really don't want you to take anything away. Note the very tall fence they have to prevent anyone from "Rescuing" any old computers or parts.

Actually, I do still use a 775 system for winXP and going from Fsb333 to Fsb400 can be 'felt' even in the loading times and the startup of Windows (faster loading times and overall snappier feeling/performance), it's very easy to do also.

I saved most of the stuff from Intel in a about 20 archives. Your boards docs and last bios are in this one:
https://archive.org/details/intellegacyboards3138
you can browse the RAR and grab the files you want seperately: https://ia902805.us.archive.org/view_archive. … rds%2031_38.rar
the DP35DP_QuickRef04.pdf is very handy for the pinouts of near all the board connectors....

That's a terrible policy considering that the "reuse" is the most important part of recycling. They probably have a hoader on staff that is picking through the e-waste for valuable stuff and trying to block anyone else from getting it. You can tell by the handwritten sign that it's probably that.

Unless it's considered theft, I would personally just ignore the sign unless someone came out and told me not to do it in person.

They definitely consider it to be theft. As I've mentioned before, their old facility was too small, and stuff would overflow out to the front where it was completely unsecured. I would stop by when they were closed and scrounge, but one evening I stopped by just a little too early and they were still open. No one was out front so I began looking through the pile of stuff, and a guy came out and told me "You can't take anything from here", so I left and came back a little later.

🤣 current average in USA for certain computer parts scrap value: HD's $0.50/Lb, MB $1.75/Lb, PSU $0.17/Lb, PC tower $0.18/Lb. (from https://iscrapapp.com/prices/)
So you take either 10 HD's or a few PC towers plus a motherboard at around 5 Lbs total and you stole maybe it worth about $5 and they would prosecute for theft 🤣
Yeah but you can shit on street and break windows under the Justice Warrior clauses and not be prosecuted at all... what a world we live in...
Long ago I knew a true story of someone taking about $4 worth of cans (@ 10 cents a can) and got prosecuted for it so maybe it is possible.

In most states its petty theft if the value is under $50, probably a small fine. In my state they can't even use force against you, 🤣 you could literally just refuse to ID yourself and walk away unless the cops can cook up other probable cause to stop you. I guess it depends on if they go by scrap value (arguably the more applicable measurement if your taking from a recycler) or eBay value. By eBay value if you steal a 486 it could be felony theft in some states where $500 is the bar for that.

(For legal reasons I must disclaim that it is illegal to steal, and that this is merely a statement of fact and not an encouragement to the commission of any crime state or federal. Please follow all locally applicable laws and regulations)
