 		 #111254 - Maybe I can help ...
Responding to: ???'s previous message
Depending on how many signals, the voltage levels, and the desired sample rate, perhaps I can help. I've not only built complete logic analyzers, (quite a long time ago) but have also built small samplers that use simple logic and RAM to feed multiple stored signals to an oscilloscope for viewing. That's not exactly a logic analyzer, but its often handy in debugging short, quick, infrequently recurring events involving multiple signals.

If you can let me know what your requirements are, and what equipment you have available (hopefully including an oscilloscope) then perhaps I have some help for you.
