Here are my findings after a couple of days of tinkering. 1) The main things I'd like to change are clock and multiplier, since I'll be using different 486 cpus with this board. 2) I tried both DX, DX2 and DX4 cpus. For 1), I believe that the clock generator is an MX8315 in SOP 14 surface mounted …

Hello everyone! I found this working IBM Socket 3 Motherboard, but I can't figure out the model. I want to mess a little with the jumper settings, but I have no manual for it. Any ideas? Anything you could tell me about this board would be greatly appreciated! Thanks!

I can only guess at this point. The mixer seems to have a data connection to the mainboard (the cable with the 5 seperate wires from the mixer to the mainboard). I can imagine that it has to be switched from TV mode to PC mode or something like that. So that both sources dont play at the same time. …

Ok. So you want to try to get it working in the original system. That was the information i was missing, i thought you wanted it to run in another system. We can have 2 problems. First the sound card does not make sounds. Second the mixer is not set up properly to enable the soundcard input. If you …

That’s a great idea. I’ll try that this week. How would I have it work in DOS/W3.11? First try to get some sound from it. Sometimes driver install fine and you still dont have sound. If the drivers work windows98 and the type of card is confirmed working, you can install the dos/w3.1 drivers for …

Update: managed to get it to work in W98 in a different pc. Since it doesn’t have any output that I can plug in there, I could only try line in and it works okay. Here is a list of the drivers that it’s loading. Any ideas?

FYI Windows 95 recognized it as a Washington 16. It loads the drivers automatically but no sound. The AZT chip is common with a Washington and apprently the device ids are the same as well but the Codecs are definitely different and those drivers won't get any sound from this card. Please try the …

Thanks! Do you think it would be feasible to add an external speaker port on the back? The pads seem to be there, but they are unpopulated.

Well, I can! Haha Unfortunately, the manufacturer does not provide any support (just called them) since it’s so old (a sticker says 95). If it indeed is an ibm machine underneath, how would I go and find the correct model for the BIOS disk? Edit: more pictures from the guts of the beast! IMG_3498. …
