Has anyone used Winscope for digital circuit analysis? Is it a
useful tool? If so, what voltage levels are safe to input into the
line input jack on a PC sound card? I would be measuring TTL logic
levels. Any problems doing this?

TIA for any help.

    Take a look at the Optascope at www.parallax.com. Great little scope - has a
    max input of 40 volts wothout the attenuator. Dual channel - USB connected.

    A very nice little freeware utility. I've used it with TTL logic
    levels but not much higher. You might want to check with your
    soundcard manufacturer first for maximum input specs.
