Wow! All three archives gave you an error? Amazing... what bad luck you have with searching for your own answer rather than just asking us. I just searched for servo at the FAQ site at found two pages: http://www.piclist.com/../io/servo for general information on servos and http://www.piclist.com/../microchip/a2d-step-rw for PIC source. Maybe they will help. The iversoft archive does seem to be down, and I (as I'm sure you also did) sent an email to the webmaster of that site to let them know. Also, the archive at http://www.infosite.com/~jkeyzer/piclist/index.html seems to be working again. It returned 716 hits for "servo" and sending "search servo in piclist" to listserv@mitvma.mit.edu resulted in just a few more.

(I get a error when searching the archives) 1. The servo (FUTABA S100) has three wires (red, black and white). Can someone help me with the connections (eg. black - gnd; red - +5V; and white +5V signal from pic???) 2. As I understand the servo move one increment in one direction when a 100ms pulse is applied and in the opposite direction if a 200ms pulse is applied? 3. Is there some feedback from the servo that you can determine the position of the rotor (if not how does the servo know the center position every time I switch it on in the aircraft?
