The front bezel with the type designation was nowhere to be found - apart from that, the unit looks just like the one at http://www.science.uva.nl/museum/tek4002a.html Thanks in advance, yours sincerely -- Arno Kletzander ---------------------------------------- Hey - Great site. Thanks for the reference. I especially like the scans of old instruction cards, one of my favorite pieces of collectable history. Billy http://www.science.uva.nl/museum/instr_ref_cards.html
