Here's a photo of an interesting example of (I presume) #2 for a PDP-15 in a japanese computer museum. Also note the unusual PDP-11/05 masthead arranged as 'PDP11-05' with a unichannel 15, and also one of those nice blinkenlights panels Noel has documented: http://www.kcg.ac.jp/museum/computer/images/mini_computers/dec/vax11_780.jpg Steve.
