4 is this 386 with an AMD 40, the battery on this was old but it did not leak at all. Powers on but it would not post so, I removed the old one and soldered in a new one, it still does not post, I don't know if jumper settings are the reason. 30304306-FA3003A, Ali M1419 A1,

5 this one I think works but do not remember it is missing the bios chip and I was wondering what kind of bios chip can I put in this to test it with? and is this board worth rebuilding if it works?
486 PAT48AV-1.40, Ali M1429 A1,

6 this board I do not remember if it worked it is missing the bios and Keyboard bios I think is the the missing chip? It has corrosion that is bad but hasn't ate through the board yet, I think I can clean it all off but is it worth cleaning and rebuilding? and if so what bios and keyboard chip can I use for it? TK-82C480A-4S-D01A A1, UM982C481BF, UM82C482AF

7 this board I don't know if works not sure how to power it up. NEC G8KGC, ASSY 158-026115, what caught my eye is Tseng ET4000AX built on!

8 up is the 186 I think? don't know how to power it on, Technology System Board, ASSY 990078-03 Rev M7, Wyse Tech D8742 Intel.

9 is this 286, System Board 256 / 512K, 6480148-XM, 6480087.

10 works I was wondering if anyone could tell me what it is, I did search and found nothing it is, ATronics Int'l S/N 93091376, Master Rev.A-3
Bios string 40-1200-001156-00101111-060692-USA-9204-H

486 PAT48AV-1.40 needs indeed a new bios chip.. Originally it need to have and AMI bios for 486 DX

For your first board, i think it needs a special riserboard so it would give you the ISA slots (because they arent soldered to the board) This board also needs a seperate graphics cards, and also a special AT style case.
A normal AT style or baby AT wont fitt this board.. I also seeing that is missing the bios chips.. If you cant use it i would recommend to sell it. I also think its an OEM motherboard.. Maybe from C&T (chips and technologies) it self.

The second board can be usefull.. Its a earlier 486 motherboard, so it accepts only 30 pin FPM simms and having only a 5volt line to the processors.. The max processor should at least be a 66mhz one.

SIxth board, i think its an ADI motherboard. and indeed its missing the bios and the keyboard bios chips.. i think this one would easy to clean with vinegar.. And UMC chips are very compatible with hardware and could be very fast too. Diffently worth to keep it if you can restore it.

Ref Board 10; may well be an 'Atronics International Inc.' motherboard - if
there is not a designation ATI-xxxx on it, then MASTER is probably the model ID,
as about 1992/1993 Atronics was using single word designation (e.g. ATI-IDEAL ,
to ID the model of its add-in cards).
The chipset "USA i" is a 'USA Integration SC-9204' . (SC9204)
A similar or same motherboard was used in this computer system:
ATronics ATI-486 Multi Media;
https://books.google.com/books?id=nhSywJ4rn6UC&pg=PA150.html
(except that that system has the next newest AMI bios for the SC9204 chipset).
https://books.google.com/books?id=nhSywJ4rn6UC&pg=PA198.html

The layout of your motherboard is almost identical to this record;
http://museum.ttrk.ee/th99/m/U-Z/31843.htm
except that yours has a jumper 15 (JMP15).
Probably most, perhaps all, the information in this manual would be applicable
to your motherboard (except for their manuals 'out of date' bios description);
http://www.elhvb.com/mobokive/Archive/Unknown … 6/vlbus3486.pdf

(The 'Quantra' sticker presumably refers to Quantra Labs, out in Santa Clara,
whose only relevance here would be as a former owner/OEM of your motherboard.)

The third one is quite rare, it features a socket for Weitek CPU and can be sold for good money if you find a buyer. A stupid question considering POST... Did you insert the CPU?

Here's the fourth one

I got the one with the AMD built in working, thank you!

You mean the one with the Wyse logos? Is that a 286 and what speed CPU should I test it with?

I found the riser board that gives ISA for the first motherboard I turned it on and then realized the bios chips are missing. It does power on though.

Very solid board as far as I see it, have fun!

3 is this 386, when I got this the battery had been removed and there was only a little spot of corrosion I cleaned it up and soldered a new battery in but I can not get it to post I don't know why or what else to check on the board that could be stopping it. I don't know too much about the jumper settings. Opti F8C206, 82C496, no other markings on the board.

The Wyse motherboard seems to be a 286. Picking the right CPU is not hard, but how do you power it up?

1. Low Profile 12MHz 286 board (10MHz CPU, 20MHz OSC). Missing BIOS chips. May be salvageable if you can get BIOS images that use the same chipset. Looks to be a clone of an NEC Powermate.
2. Symphony Based 486. Good DRAM performance (interleaved). Only downside is no local bus. Silkscreen is present, so manual probably useless.
3. OPTi 496 386 should have 8kb integrated cache like the MX chipset. Simple board, should be easy to figure out jumpers.
4. Late model ALi based 386. Takes up to 256kb cache, and CPU/FPU not soldered. Few jumpers. Good.
http://www.uncreativelabs.de/th99/m/A-B/31330.htm
5. VLB based ALi 486. Should be decent if you get a new BIOS (not difficult). Made by TMC Research.
http://www.uncreativelabs.de/th99/m/S-T/32898.htm (jumpers on this board should be the same as yours, only memory slots are different)
6. PCB looks like decent quality. Interesting memory configuration. Corrosion problem is serious. Missing KB controller and BIOS. Junk.
http://www.uncreativelabs.de/th99/m/I-L/30046.htm
7. Low profile 386DX with cache, integrated video and I/O. A great board if you could find a chassis for it.
http://www.uncreativelabs.de/th99/m/M-O/32194.htm (pretty close)
8. Wyse 286. Probably 8MHz. Likely 512kb RAM. LCC CPU retaining clip is missing
9. Type 1 IBM 286 AT system board. 512kb in special piggy back DRAM
http://www.uncreativelabs.de/th99/m/S-T/32898.htm
10. Don't know anything about this board or chipset. Could be converted to a 386 if you soldered in the sockets though. Might be interesting since it has VLB. Looks like it could have come from an OEM called "Quantra"

The one with the Blue Socket in the middle? I tried it last night and got it to work there was an IBM 80286 XC CPU that came from it originally. I could not figure how to get in the bios though. It does have IBM Basic.

No clue. I'm going to check and see if I have that PSU but I doubt I do.

For the BIOS, check these; http://gluek.info/wiki/hardware/howto-enter-bios-hotkeys

Or just hammer keys, I've seen some boards with weird combinations over the years. You might have to make your own PSU connector for that Wyse, you can find the pinouts easily with a multimeter by checking for continuity to known power and ground pins for devices and slots/connectors on the motherboard.

Some very nice boards. If you ever want to sell that ATronics...

IBM 5170 motherboards do not have a built in BIOS setup. You need to use a reference disk. The other option is to swap out the original BIOS chips with an AMI replacement.

Oh, so it's one of those?
Well in that case the solution is simple;

J/K

Yeah. Except that it might be the most valuable motherboard in the whole pile in terms of resale value.
