When did Silent Circuit first go into production?

When did Silent Circuit first go into production? Just curious after having seen some AL pics without the battery compartment.

Well, it had to be after 1996, because my AL doesn't have one.

The Silent Circuit was used on Silhouette Specials and Axis Sports long before Albert ever adopted it for his signature axe... Albert Lees didn't come with the Silent Circuit until 2001.

My Axis Sport has a build year of '97 and it's got the circuit, but I'm fairly sure it was around on the silo's for some time before then....?
