    Default Unusual find in an old 286 that has been untouched in years.

    Found this Videc IO card in an old 286. I have never had or seen one before. Anyone else ran across one?

    It will not let me upload the pic to the forum, file size too big. Any suggestions on a site to share and link here?

    Lets try this link:

    Helping a great community where I can! I was able to view the link and have attached a copy.
    The ibb.co link above is 3x the resolution if you need a clearer picture.

    It looks like the usual Mono or CGA card with LPT port.

    64KB of video RAM, an EPROM chip (character generator ROM), and a total of 9 PALs... it's most likely an early Hercules clone.

    It's hard to read the oscillator frequency from the photo. Looks like "22.0 MHZ" to me, whereas for a Herc clone I'd expect it to be a 16.000 or 32.000 Mhz....

    It has 64k on it so I'm going to guess Hercules compatible mono card. (I can't read the writing on the crystal, if it's 16mhz then it's pretty much a sure thing.)

    Looks to me like it might be a badly smudged 32.0 MHz, but it's admittedly really hard to tell with any confidence:
