    Mid Atlantic PC Motherboard Diagnostics Needed

    I have three boards from 1999, all exactly the same. One still boots/posts but the other two have issues. While I can’t find schematics presently, I hope the “working” board can provide enough info to compare and determine what is wrong. I am trying to find someone who can do such work, either...

    Compaq Prolinea 4/25s 4/33s Motherboard

    Thanks, much appreciated. If you have a multi-meter capable of taking readings for the various components, and are willing to, that would be much appreciated as well.

    Compaq Prolinea 4/25s 4/33s Motherboard

    Not sure. It was stored in a dry, indoor settings, but one spot developed corrosion. Nothing was near it that could cause it. I had removed the battery long ago before storage. The case is all good as well, no signs of corrosion or rust. Best hypothesis...a bug crawled in and died. Its...

    Compaq Prolinea 4/25s 4/33s Motherboard

    Much appreciated. Hopefully the 4/66 uses the same motherboard as the 4/25s or 4/33s.

    Compaq Prolinea 4/25s 4/33s Motherboard

    I've found that MUSIC chip is the onboard VGA namely a DAC. Everything in that area is related to the onboard graphics.

    Would someone happen to have motherboard schematics documentation for the Compaq Prolinea 4/25s 4/33s Motherboard? I've searched online, but I've been unable to find any. Many thanks in advance!

    Compaq Prolinea 4/25s 4/33s Motherboard

    I have one of these Compaqs that I’m trying to restore. Mine has some corrosion damage on a few components. Would anyone happen to have one of these systems as well? If so, would you be willing to take high resolution, close up pictures of the motherboard? Taking readings with a multi-meter on...

    5.25 Floppy Drive - Jumper Settings

    I acquired two vintage 5.25 floppy drives. I want to hook them to "modern" motherboards I have. Both motherboards have a single-drive floppy controller that supports all types of 5.25 & 3.5 floppy drives. I need assistance in getting the jumpers set correctly to work with these motherboards...
