    On the other hand, some of the software is excellent.  Boulder
    Creek Engineering, for instance, sells a pocket-size logic
    analyzer that plugs into a PC's serial port (and another one
    that plugs into a USB port)... The software (which acts as a
    demo if you don't have their hardware) is available at:

    I have one of their 8020 logic analyzers... The serial interface
    makes it a little slow, but other than that, it's a great little
    product.
