AD-I08B

Be aware that whether you buy this one or another, you WILL have to repin the female pin header block before plugging it in to the motherboard.

Do not trust colors, use a multimeter.

I know nothing about repinning or soldering unfortunately.

No soldering required. You just take the contacts out of the housing and move them around

That motherboard is stuck in AT-era hell. The 5-pin DIN is ancient, and there’s no standard PS/2 bracket that just uses a header, what eBay calls “PS/2 brackets” are almost always PCI cards.

I found one on Ebay under this description: "PS/2 Mini-Din 6Pin Female to 2x5 IDC Female Motherboard Header Adapter w/Bracket."

And here are typical PS/2 mouse header pinouts, your is likely one of these.

I've never done anything like that though, or have a multimeter. What about a serial bracket? Would I need to do anything like that with this: https://www.ebay.com.au/itm/236253940936?

I bought what you are looking for brand new from an eBay seller late last year. Had to rewire the pins as mentioned above. As mentioned there is no soldering required you just pull the cables gently from the connector while lifting the plastic tab that secure it and rearrange it to match what your mobo is expecting.

I will send you the link in PM.

Edit: gosh I just realized that between November 04 and now the price has increased by almost 3USD !

I get it now, but how do I know which wires are which?

I bought one to attach to my Asus TXP4. The first step was determining the layout of the board header, then arranging the pins in the holder to match. As the color coding for the wires did not match the standard, I had to use my meter to check continuity, noting which color was at which position. The photo below is for a USB harness, but the cable holder is the same, the same method applies.

This is why (certainly one of the reasons) everyone was happy when ATX replaced AT.

Well I ordered it, but should I buy a multimeter I'd have no idea what to do.

You're in luck, the manual for your board shows the mouse pin out. You will need to make sure that the pins match this - accidentally connecting the +5 to ground would be bad, so having a voltmeter to ensure that doesn't happen would be a very good idea. The most basic one would do.

Also, manuals can be mistaken, they can change things between board revisions, etc. As they say in carpentry "Think three times, measure twice, cut once."

The multimeter is simply to help you make sure the pins are in the right order to match the socket on the motherboard. If you don't have one just ask around you, those things are fairly common.

Worst case scenario you buy one, it cost 10-15 bucks, it's always a useful tool to have at home.
