80x25 text terminal with T.V. out - possible, or no?

I need 80x25 text to emulate a DOS text mode screen. Can the Propeller do this with TV out? I don't care if the font looks terrible, as long as I can read it. Is there a technical limitation preventing this text resolution on TV out, or is it just that no one has been interested in writing one?

    It is theoretically possible, but would look HORRIBLE

    - you'd have to run interlaced mode
    - best bet would be disabling the color burst signal and making a 640 wide luminance-only signal on each scan line

    It will look really bad.

    40x24 is MUCH more doable, and can look ok (sort of)

    Best,

    Bill
