Wow, good spot! This one isn’t badged but we just assumed it had fallen 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: http://bitsavers.trailing-edge.com/pdf/learSiegler/ADM_3/DP2880486F_ADM3A_UM_Apr86.pdf <http://bitsavers.trailing-edge.com/pdf/learSiegler/ADM_3/DP2880486F_ADM3A_UM_Apr86.pdf> I do love a happy ending to a search :) Cheers! -- adrian/witchy Owner of Binary Dinosaurs, the UK's biggest home computer collection? t: @binarydinosaurs f: facebook.com/binarydinosaurs w: www.binarydinosaurs.co.uk
