I would disassemble it completely first. Next thing to do is to remove that old battery, and check if there is any damage on the board because of that. Then a good cleaning is all it needs. I usually remove all the plastic parts, and wash them using water and soap.

A 286 should run fine windows 3.0 or even 3.1 .

I think you can use it. That empty socket probably is for a 486DLC, but maybe it can be used for a co-processor. If you want to make sure it works that way, check for any jumpers indicating something fpu or 387, and also check the bios setup for any options. edit : Now that I watch it again, I'm …

Re: ATX to AT converter cable power buttons & acceptable voltage range?

Which converter do you use Markk? Don't ATX power supplies use momentary switches? Short briefly to turn on, and again to turn off? If you use an AT switch wouldn't that just either close the circuit or open it? If you keep the leads shorted on any of my ATX power supplies it'll turn on the …

The AT power button has four cables that are connected directly to the mains power outlet, so you should be very careful and not touch those when it's connected. The ATX psu is different. Power goes in, and there only a switch to activate it. I guess if you want to use an AT case power switch it's …

Can somebody tell me. I found an picture on ebay.

First, I'm not the guy from ebay. At least I didn't have any mail so far. So let me see. By reading your description, I think you might have to try with a different video card. If I remember well, not all of my ISA vgas would work on that. I found just 2 that would be fine. The trident 8900 might …

Robin4 I had bought the same board from the same seller a year ago. Mine worked fine. First tell us what kind of video card did you use. As far as the ram chips are concerned, I remember using 8 chips for a total of 1MB, which I had from a broken ISA svga card. Also keep in mind that you need a …

I remember some time ago, when I've been trying to play the "Aladdin" game. It wouldn't play on my pentium and pentium 3 pcs. The first had 128MB RAM and the second 512MB. It would display the message "xms allocation error....". I remember back in 1995 I would play that game fine on my pentium 100 …

Great build and great presentation! I love 286s! That's indeed a PC you would buy in 1988 or so. My 286 is somewhat more modern(it has simm sockets, 16MHz cpu, VGA card and IDE disk), but I wanted it to be like my first 286 pc which was bought in 1991.

There is another way to force pc speaker sound. The game has 2 files for that (ibm_snd1.dat and ibm_snd2.dat) , and 2 files for adlib/sb sound (midisnd1.dat and midisnd2.dat). If you have a sound card, it will play those midisnd files by default. So what you can do to have pc speaker sound, is to …

I don't think so. I've got 4 S3 trio 64 cards I think, and one of them has also that audio out jack. However it's a good card for dos games, as it is very compatible.

No, it's a sound output that works if you attach an mpeg daughterboard I think. I guess you can connect this output and the sound card's line-in.
