Wow, good spot! This one isn?t badged but we just

off. Just as I?m typing this he?s messaged me to say it?s actually the
ADM-3A ?10th Anniversary edition?. The manual is on bitsavers:
It might have _started_ its life as an ADM-3A 10th Anniversary Edition,
but it isn't one any more. The PCB in the photo is the Zentec ADM3 Retrofit.
I may have been completely wrong about that. 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.
