Hi all, I have this 8Bit ISA Card but cant figure it out what it might be. It has 15pin D-Sub connector (like VGA), Composite and what I presume S-Video like connector. Doesn't seem a video card at all, even though it has Video card output connectors. Was this perhaps used as a capturing device of …

50pF seems a more reasonable now that I come think of it. Thanks 😀

Hi all, I'm looking to restore a 386 Motherboard that has suffered from leaky Varta battery. The damage is not very wide spread so there is a chance. Need to fix a few traces but should be doable. Also Tantalum capacitors need to be replaced, one of them went pop on me so I'll just replace them all …

Hi all, I have this Compaq D815E. Seems like a very interesting motherboard with support for Tualatin CPUs and also has Intel i752 on-board graphics. Unfortunately it won't power with standard ATX PSU because of different pinout. I did some research but cannot seem to find an exact pinout for this …

It is a Tantalum capacitor (value = 4.7uF/16V). It is common for these to go bang with time. Nothing to worry, most of the time they just fail this way but don't take anything with them. So just replace the capacitor (or just remove it completely) and the board should start right up. Also it would …

Did you put CR2032 battery into place? Some motherboards don't post when it is missing.

Today I purchased a MB 486, I thought it was an EISA ISA, in reality I discovered that the EISA is an OPTI, I honestly don't know what the difference is, could it be the same thing? It already has some 30 pin RAM, some L2 cache chips, I think it's 128KB, and an Intel 486DX2-66 CPU, I don't think …

Hello there! I think you're trying an ESS cards that doesn't have DOS support. I'm not an expert, but from what I remember, there was a video that Phil from Philscomputerlab did, and he mentioned about something that ESS cut support starting from the Allegro card and onward, so the last DOS card …

Do you have an ESR meter? Some multimeters will measure Capacitance. Also there are those cheap cinese LCR-T4 testers that are quite good for testing capacitors. Maybe you could pull out 3-4 capacitors at random, especially those near the CPU are and see if they still are good. The board is from the …

From my testings the Virge/DX cannot run 3Dmark99, you can use Final Reality (on board accelerator) if you want to test the card.

I changed it this morning. Found the component on a broken board and replaced. It worked on first try. Again thank you very much!!! Given the limited space and my cheap soldering tools it came out ok 😁
