     Some of the elecronics magazines, including Electronics Now, have done
     construction projects recently, some better than others (the EN one was
     quite good). Also I am pretty sure I saw a few more construction projects
     on the WWW a while ago, but I can't find them now.

Subject: [OT] Cheap logic analyzer using a PC

Greetings PICers,

This is completely OT but if anyone knows of any software written to
somehow use the parallel port or the serial port on a PC as a logic
analyzer. I only need to have a single channel and need to be able to
capture and save the incoming data stream for a period of atleast 5 secs.
The data stream is being clocked at about 40 KHz.

Please send responses back to sheikh@erols.com. Thanks a bunches.
