    Default Unknown ISA Card

    I pulled this card out of a 386 machine I picked up a while back, and I can't figure out what it is or what capabilities it has. It has a VGA connector, and what looks like a connector for either cgs, mda, or ega. Can anyone ID this thing and maybe shed some light on what it can actually do?

    I have a very similar Oak card.

    It can do VGA and EGA.

    A card that looks basically like this one is among the many listed on this page. Looks like it's a basic 256KB EGA/VGA card, so presumably that 9-pin connector is for EGA modes.

    Gosh, I forgot VGA-9 was a thing that existed.

    Wow, very strange. I've never even heard of VGA-9. I guess that clears it up.

    Yep. A lot of multisync VGA's were 9-pin. Have an old Texas Instruments monitor (probably in a sad state) that was 9-pin VGA. It was a nightmare getting it in vertical sync on a standard PC and as I recall it weighed almost twice as much as a similar "standard" 14" VGA CRT monitor.

    That is because they can be used with EGA and CGA cards which are 9 pin as well as 15 pin VGA cards for which they use a 9-15 pin adapter.

    Better yet, the 9-pin VGA is almost identical to the PGC, only with two separate sync lines instead of the one composite sync line. Many VGA monitors will still take composite sync, making them PGC compatible!

    Can't find this exact card, but similar OAK cards typically use the 9-pin connector for TTL monitors, of any type: MDA, CGA, EGA.
