Hi folks, I've noticed this strange extended PCI slot on some retro motherboards and was wondering what it's for? Thanks

Depends who the board is from and what it does, because it could be RAIDPort as used by the Adaptec ARO-1130CA to add RAID functionality to the onboard SCSI on certain boards, such as SuperMicro's P6DGU and S2DGU to name a couple off the top of my head. I am unsure who else, if anyone, ever used this feature, Tyan I think, possibly on the Thunder 100.

similar indeed; it seems asus installs his extension rather on the lower part and scsi is installed on one of the first ports - any other way to differenciate?

My guess would be that if the board has SCSI, it's RAIDPort. If the board does not have SCSI, it is Asus Media Bus or something we do not yet know about.

Yeah I was going to say RAIDport. This is what it looks like on a Supermicro dual slot 1 board:

On socket 7 it's indeed the asus Mediabus port. I have 4 motherboards with it either lying around or in use.
To make it more confusing there was the earlier Mediabus 1 standard on only 1 motherboard, and Mediabus 2.0 on all the other ones.
And there are some 7 or 8 different cards that used this interface.
