486SX Industrial Computer Board Cleaning & Overdrive Upgrade, Testing and Gaming

In this video I am cleaning an industrial single board computer which I found at the trash yard. Fully covered in dirt it will shine like new after my treatments. The board contains an Intel 486SX-25 and will get upgraded with an Intel DX2-66MHz OverDrive.
Explaining the board, cleaning and benchmaking is part of the video as well as playing Doom, Prince of Persia and Pinball Dreams under Microsoft DOS.
Thanks for watching.

Hi Peter, thanks for sharing this wonderful video. This is actually a SBC, which was produced by Siemens for their Sicomp PC-32F line. The board has the part numver Siemens W263361-D674-Z4-09-5. On Ebay US there is currently an offer available that shows exactly the same board.... just 950 bucks... seems you found a real treasure in the wood! Cheers Ralf

@john_ace Жыл бұрын

Siemens has used similar boards in their PCD-line. I think they made a design, that could be used in industrial as well as personal PCs. SIEMENS NIXDORF PWS M70 4gsx/25 on Ebay has the same CPU board. The rare (small desktop) PCD-4Bsx might have had the same board as well.

Frohes Neues, meine Herren! Here's an idea for both of y'all if you're up to it: see if you can source DCP, which is MS-DOS but Made in DDR. I haven't found anything where I could download e.g. DCP 3.3 (which is the equivalent to DOS 3.3) and run it at least on PCem. Even more fun would be to find DCP and an XT compatible of the VEB Robotron-Systems, like the EC1834, which ran on the Soviet 8086 clone K1810WM86 (or K1810VM86 outside of Germany).

@ruben_balea Жыл бұрын

@@bundesautobahn7 I installed DCP 3.3 on PCem, on a type 2 hard drive (20MB 615 cylinders, 4 heads, 17 sectors per track) For the floppy drive you must use a mainboard that supports 1.2MB 5.25" drives, I think all 286 and higher that PCem emulate support 1.2MB drives, I used the Award 286 clone, i can give you a copy of the disk images but the big brother may censor the address so I'll try camouflaging it a bit: mega DOT nz SLASH file SLASH v4BxlLpa#zCPsU-Ccr3HDXnlihNm49EJQptIUvAvHixRLl5CA_uc I think I installed it more or less OK but I don't speak German, I can only understand a few common words and phrases after years of buying things from Germany and Austria on eBay... I could have used Google Lens to get an instant translation but it was more exciting to get it installed on the first try whithout cheating 😉 There is a free program called SAMdisk that allows you to convert disk images from TeleDisk and many other formats to raw or various other formats, but the Windows version only works on 32-bit Windows 2000 and later, I used Windows 2000 which I had installed in a virtual machine.

Welcome back, Peter! That BIOS is pretty interesting, it looks almost like an Award BIOS for 286 computers in the POST screen, but the setup would have to be on a black screen and not in colour. Plus it looks like you enter the BIOS with STRG-ALT-INS, when the aforementioned Award BIOS would require STRG-ALT-ENTF instead. The curious thing: We had a 486 DX2-66 in a Colani-Tower from Highscreen, and the Award BIOS there was far different from the one on this single board system. At least this system is now in caring hands. And please tell good ol' Österreich I said "Hi". It's been over 30 years since I was last in Austria and would like to visit again some day.

I'm so glad to see you're back and still doing ok. Was already worried something might have happened when you went silent. And you're starting the year off with a really nice find. I have a special faible for industrial boards, and quite a few of them around from that era. As you recognized right, the long pin header goes directly to the ISA slot and was intended for a VGA add-on board, making this into a two-slot sandwich. Unfortunately, those cards are really rare as not long after, PC104 became established and replaced them.

Looks like a Siemens PCD-series (PCD-4...?) CPU card. The PCD-series had such CPU-boards until Siemens decided to make a more integrated LPX format board with most components on a mainboard. The connectors above the ISA-slot would either contain a graphics card in the newer systems or an MFM-contoller in the older systems. I have a WD graphics card and two et4000 cards for that connector. The ET4000 are for use in an Atari TT with a VME-adapter (nearly the perfect size).

@brandonupchurch7628 Жыл бұрын

The RTC module appears to be original, it's probably still good because it was used until relatively recently in a machine that ran 24/7, and when the chip is recieving 5V from the powered on machine the RTC battery is not used so that's probably why it's still good even though it's 30 years old, so if the card was in a machine powered on for almost 30 years straight the lithium cell is probably still good because the only capacity that it's lost is from self discharge which can be extremely low depending on what the average temperature the battery was exposed to.
