Pickin' up my retro motherboard today~
Oh, YES. This is the Soltek SL-75MAV. It's identical to the SL-75KAV, with one important difference: onboard ProSavage graphics! How good is it for DOS gaming? Details to come in the future, when I throw it into the retro box.
@azushark It's AGP Pro! I don't have a single AGP card that'll take advantage of the additional pins, though. But at least a regular AGP card can be used.
