The 11/74 panel I linked was one of the four CPUs (CPU C as the green sticker shows, and giant painted "C" indicates) of DEC's DAEMON system (apparently it might also have been called PHEANX?) quad processor setup. More pictures here for people to oggle and drool over: <http://oboguev.livejournal.com/2696291.html> It looks like your 11/74 panel might have been designed for a mounting similar to the other 11/74 (we'll call it DAEMON-type) panel mounting (same visual style and colour scheme) which is distinctly different from the standard 11/70 mounting (though the DAEMON panels all follow the same general layout as an 11/70), though the actual mating PCB would have been different, since the keylock and parity lights have swapped places and the display indicator LEDs have been re-arranged. > I also have a complete DEC DataSystem-570 panel (frame, plex, switches) > which is just > a standard 11/70 panel, but recolored in light blue / dark blue / gray > color scheme. > This might or might not be blasphemous to some, but I think the DDS-570 colour scheme looks much nicer than the standard PDP-11 colour scheme. Hmm, now I'm wondering how close of a match the "business system" blue PDP-11/7x models match up against DEC's other blue coloured systems; i.e. KL10s of the DECsystem-10xx flavour, PDP-15s, and the alternate blue-coloured PDP-12 (<http://www.technikum29.de/shared/photos/rechnertechnik/dec/konsole,hell.jpg>). Actually speaking of the KL10, I forgot about the fact it's front-end processor was a PDP-11/40 with an alternate colour scheme panel. Cheers, Christian -- Christian M.
