    Default What Motherboard does this thing go to?

    I've got this rather odd PCI Controller Card with a Floppy Drive Port / 2 IDE Hard Drive Ports / 2 Serial Ports / 1 Parallel Port / 1 Game Port with a Paddle Card that plugs into a 16 Bit ISA Slot, and I'm trying to figure out what Motherboards it was designed to be used in.

    Anyone have any input on identifying this card and what it goes to?

    That's ISA not VLB.

    The ISA is almost certainly for the floppy support (and probably other devices) as well. Floppy requires legacy (ISA) DMA for operation--while it's not impossible, it's a bear to implement a legacy-compatible PCI floppy controller. Usually involves a PCI-ISA bridge.

    You are correct Sir! I stand corrected. (Fixed the post too.)

    Weird card, indeed.
    I think you can use it with any ISA+PCI mobo.
    Why did they make it like this, instead of simply providing one PCI card, and one ISA?
    Maybe for some compact case, where there's no room for two full-height cards?
    Or for those "shared slots", where ISA and PCI slots are so close together, that you can't install two normal cards at the same time?

    It's cheaper to produce one card with all the logic, and just have a daughter card with no logic that's small, rather than 2 full cards with logic on it.

    I agree with Chuck, that ISA daughter card is definitely for the floppy drive. Following the traces from the floppy connector lead to the Winbond IC, and that goes to the ISA connector.

    I think I had a Motherboard that it went to at one point in time, either a 486 Motherboard or Early Pentium VLB Motherboard that didn't have any FDD / HHD or I/O Controller built into it.

    I've seen one of these before described as a "PCI Floppy Controller". It was missing the ribbon cable-to-ISA dingus. My only response was "Get back to me on how well it works..."

    Never did get a follow-up.

    DING! DING! I might have a winner here. Not necessarily the ONLY Motherboard that could use this, but definitely one that NEEDS this.
