Yeah, looks like it. I will test some stuff tomorrow. I don't really expect anything to work anyway 😀

I uploaded some of your images in their respective pages we have 😀

http://www.win3x.org/uh19/motherboard/show/3238

Now for your second suntac 286 I noticed something very strange.

It looks exactly like my 286 that I uploaded here http://www.win3x.org/uh19/motherboard/show/456
However mine has "286H" mention, and yours doesn't ... But it doesn't end here !
Your ROM says "KP286HF" ... but this is actually a motherboard name !
http://www.win3x.org/uh19/motherboard/show/3839
But the board has a different layout ... What the hell ?

As for the Microstar 286 board, I can already tell that it won't work ... Someone seems to have taken off the crystals from your board x) (maybe even more stuff is missing ? who knows). Crystals are cheap and easy to install tho, so it might be worth trying new crystals 😀

Will you dump the bioses ?

Great work on the pages. I have plenty more similar images of my motherboards. I can upload them somewhere.

Also:
http://www.win3x.org/uh19/motherboard/show/456 - this is so-called Suntac 286P (TH99 calls it that), not 286H. Bioses may have been swapped in the past. This motherboard works OK. The other suntac doesn't seem to work.

J-Bond fortunatelly works fine, so is the Soyo SY-5T 430HX mobo. VLB 486 seems pretty much dead (although CPU gets warm, no activity on the postcard though), XT motherboard seems dead (but it had ISA pin 9 - +12V shorted to data pin, so I guess it's fried), yeah I noticed the NEAT is missing OSCs and one of the chips, but I have some broken NEAT motherboards so I may try to fix it in the future...

I will dump BIOSes but it will take me a while, I don't have time for this right now...

Well my board says "286H"

And also, TH99 also has 286H http://www.uncreativelabs.de/th99/m/A-B/31636.htm

286P is here http://www.win3x.org/uh19/motherboard/show/5223

The truth is ... it must be both. These two schemas must be duplicates, some boards have been sold under multiple brands (or cloned by another). It might be the case for this one leading to two nearly identical schemas in TH99 (which then got replicated in UH19 since it's using the same base). With the experience we gained going through thousands of boards, I can tell you that this is pretty common ^^

Odd graphic card (perhaps EGA), Ultrastor ESDI controller, WDC MFM controller

Definitely not EGA. Look at the high-frequency oscillator chips: Up to 55.25 MHz. EGA uses 14.318 MHz (usually from the ISA bus) and 16.257 MHz (from an oscillator on the card). Also, this card has video RAM of the more expensive VRAM type instead of the slightly simpler DRAM type video memory. There are two reasons to use VRAM: Either the card is a high-performance card that can't get the desired resolution with classic DRAM (that's the normal reason to use VRAM), or VRAM is used to allow for a lower chip count and less complicated logic circuits to reduce PCB size and manufacturing cost (that's why IBM's MCGA uses VRAM). In your case, it's definitely a card in the high-performance area at that time.

My guess would be a non-CGA/EGA/VGA card for a high-resolution monitor used for Desktop Publishing or something like that. Most likely not CAD/CAM, as high-resolution CAD/CAM cards have their own processor to accelerate drawing - this card doesn't seem like a high-end accelerator.

From the sticker barely readable: ADI AD-1701-xxxx ??? (if I read it correct) so possibly an Analog Devices product though the chip numbers lead nowhere . For what it is worth have a Ahead EGA Wizard card with 36, 27 and 16.257Mhz Xtals and a Hedaka 622 CGA, EGA, VGA card with 4 Xtals ranging from 25 mhz thru 40. Never seen a ISA vid card with Xtals faster than 40Mhz yet until now with a 9 pin DIN, maybe a special Multi-sync card for a multi-sync monitor ??

Not a bad guess. The two main chips on the board are custom ASICs made by LSI Logic: L1A4220 and L1A4678. Searching for these brings us to a page describing the Cornerstone ImageAccel MC164 video card, which is an MCA adapter card that uses these two chips along with an FPGA to drive some custom high-resolution Cornerstone displays.

The text on the ASICs also says "CTI-CVC2" and "CTI DAT1", and the "CTI" could presumably stand for Cornerstone...

Yes, that's probably what you say. Those motherboards were cloned by companies multiple times. For example look at the picture below...

Probably it's a good guess. I only found similar card here: https://www.google.com/imgres?imgurl=https%3A … bMQMygAegQIARAu

Also this card has hand-written inscription on the back saying "controller for a big monitor".

Yeah, unfortunatelly the 20MHz one doesn't work (it tries but fails early in the POST).

Hold on to it. It might be very well fixable. Have tried any troubleshooting on that board?

Yeah, I'm not throwing it out. I havn't done much troubleshooting yet, I just reseated the socketed chips, swapped memory chips to a know good set and moved some jumpers but it didn't changed much. Board is marked as "good" so I guess it worked when it was put to storage. I might replace the electrolytic caps as this one doesn't have any tantalum caps on it.

I found some disks with software for this card. I will look at them later this week. Maybe it will shed some light on what it is exactly...

Found this 386 Single Board Computer at my father's place of work. I don't even know how to power this thing on.

Neat! Google 'pluggable terminal block' for something to match that green connector. Be aware there are numerous sizes.

Manual : https://docs.rs-online.com/1029/0900766b80028970.pdf

Looks like you can get away with just the 5V line to get it up and running.

Yeah, I've been staring at this thing trying to figure out how to get a image out of it.

Guess I'll talk more about the P4 I mentioned in another thread....got it from a coworker....

2003-2004ish Dell Dimension 3000
- Intel Pentiun 4, 2.8GHz
- 2GB of RAM IIRC
- 80GB HDD (WD800 series)
- DVD-RW Drive
- Intel 82865G Graphics Controller
- SoundMax Integrated AUdio (with Legacy Codecs.....so I guess this makes a good "Retrogaming candidate"

SOFTWARE
- Windows Vista Home Basic 32bit SP1 Dell REcovery Disk (not original, this machine is for XP)
- Licence and Key for Windowx XP Home ( ;P, I have XP Pro x86 at home that I paid $200 for in 2008)
- Drivers and stuff for Dell Inspiron Portable....not sure what model
- Cyberlink Power DVD (Dell Disc of course)
- Roxio CD Creator DE 10.2
- Dell Media Direct for Inspiron
- Microsoft Office Professional 2003 w/ Business Contact Update
- Logitech Control Center and DRivers (2 CDs)
- Paint Shop Photo Album

As for what I'm doing with this thing.....I'm not 100% sure yet. But I plan to wipe it and do something "Retro" with it so I'll continue in my "Creeping NEt Builds" thread - and I promise this time to keep it a tad more, uh, brief.

Nice 😀 That is a PC104 motherboard. You can stack PC104 extention cards (ISA in a pin header format) on top (e.g. network or audio).
Like this:

Cool PC, creepingnet.
I have a 3000 as well
It's a great PC but the downside is unfortunately it has no AGP slot.
I had a genuine intel 865 CD, which worked for the chipset and video drivers, but I had to use the Dell site I think for the audio drivers.
Because I have a few other PCs, I felt the 3000 fits a need as a mini network file server.
What's your thoughts for yours?

Well, right now it's up and running on my old XP Licence, activated (had to hack the registry for that one), with Office 2003 on it (yep, I still like using old versions of office from time to time). Right now I'm installing the MajorGeeks Unofficial SP4, which I have a feeling is going to take awhile. I also put Sonic DVD Burner software and PowerDVD just for nostalgia, and also being a musician maybe I'll burn some music to it at some point (sometimes I dabble in making music with old hardware as well I have a 486 DX4-100 that's a functional DAW with Cakewalk and a 80GB HDD running in PIO-4).

I'm actually quite impressed with it so far. XP Install took about 20 minutes, maybe 30 max, which is insane as that bests the 4600 my Wife had which had twice as much RAM but had the same Case, and AGP, and SATA (the 3000 is PATA only). But I also took the old 80GB drive out (it's going in my NEC Docking Station or possibly my 486 Desktop). However, I think the 4600 was a 2GHz, and this is a 2.8 GHz, and I also threw an mSATA 128GB SSD in there in a mSATA to PATA 44 pin drive converter box with a 44 pin to 40 pin standard ATA converter.

Right now I'm thinking this box will be a 1999-2007 era gaming box. I had a few problems running some older software on 10 recently, and some problems running that same software on my NEC Versa P/75 and NEC Ready 9522 (just not enough graphics oomph on those two Pentiums). It's pretty much factory stock save for the HDD now.
