    Hey, you can quite easily make oscilloscopes from them... :)

    So you already implemented the complete NI command set?!

    Hm, my PCI card (made by INES) uses afaicr a NEC chip, too (can't remember
    the number now). Did you ever try to ask Frank Mori Hess or one of the
    other guys who are maintaining the Linux gpib driver about datasheets?
    Should be strange if no-one has them...

    Ok, I see. Linux seems to have suffered a similar problem for some time.
    Actually it's quite a pity - gpib is really useful stuff to have in a lab.
    Well, my hacking skills are rather poor and my time is somewhat limited;
    otherwise I would already have put more effort into this.
