    It's been discussed here before. There's even one up on eBay.

    What...?

    Considering the 16-bit ISA slots, AT keyboard port, off-chip cache, and co-processor socket, it's obviously a 386 board. Was there a 386 to pentium upgrade? Or is it a good thing I usually don't bother with PC stuff? As far as I know, all PCs use the same power connector (it's between the simm and keyboard sockets) but make sure you know how to connect it, they're easy to get backwards.

    There is a remote possibility you will need a new battery.

    There were a few Pentium motherboards with VLB slots but no PCI slots. Those were for Socket 4. Need to count the pins for both sockets. It is difficult to tell the difference between Sockets 2, 3, 4, or 5 from a distant view. I am not confident that the Pentium chip is actually in a Pentium supporting socket.

    Note VLB generally means 486 was the intended processor.

    https://stason.org/TULARC/pc/motherb...SS-P5-VLB.html is one example of a Pentium with VLB motherboard just to confirm they exist. It is not the motherboard in pictures. I'm not patient enough to go through the whole lineup.

    I see OPTi 82C571 and 82C572 chips, and searching for those yields:
    https://ia801301.us.archive.org/24/i...chure_1993.pdf

    The brochure claims this is a VLB chipset that supports both 80486 and Pentium processors.

    Default Help identify make/model of CGA? card

    Pretty sure I've got a CGA card here, but can't see any markings to indicate a make and model.

    It is indeed likely a CGA clone card due to the Motorola 6845, although I've never seen one with two RCA jacks.

    No "likely"--it's CGA. Note that lack of crystals (gets its 14MHz from the ISA bus).

    Good catch! The dual RCA jacks were throwing me off; I kept looking for extra VRAM and a feature connector so I could call it an EGA card.
