Re: A standard dating back to 1987?
You're talking about the Hauppauge WinTV Celebrity full length ISA card, aren't you? I still have one - got it second hand as new it was hideously expensive. Gorgeous thing, scaling direct into the overlay without blitting to the screen (as per the later cards).
Little bit useless now analogue TV no longer exists, although it could be used to record/view composite sources etc.
