When I wrote that, I wasn't aware that Zentec bought the terminal product line from Lear Siegler in 1986, and continued making some of the terminals, including the ADM-3A, under the Zentec name. Since the LSI ADM-3A was introduced in 1976, It's possible that Zentec introduced the ADM-3A 10th Anniversary Edition with the NS405-based logic board. Eric
