Designing a homemade PC oscilloscope circuit

[sinatra]

Hello all.
Does anybody arround know about any simple, easy to build osciloscope circuit that can be interfaced to a pc (serial or parallel ports)? A homemade sampling head (not real time) would already be usefull....
My old osciloscope just stoped working and I would like to build something reasonable that could replyce it
Thanks to all.

Take a look at www.bitscope.com . You´ll find a complete osciloscope, to conect to a PC, with 2 channels at 100MHz. You can download all the project and software for it. And you can also buy some of he parts for it. I never build it but some of the comments over the net are quit good.

Yeah, Bitscope sounds good! It is not only an oscilloscope, it is
also a logic analyser and it is a open project. They are still
developing new addon modules and software for Windows and
Linux...
