Issue
When was the AC256 product discontinued?
Environment
AC256
Cause
Discontinuation notices only seem to go back to 2007, at which time the AC256 had been discontinued for quite some time. Unable to find any reference to this products discontinuation.
Resolution
The AC256 was discontinued in 1998. A reference to this can be found in the Andover Controls Network News from February 1998. On page 2 on the right hand column, there is reference to discontinued products as of May 1, 1998. You find the bulletin here.
