Seems odd they'd use the same connector for Jules> two different applications (machine to control cabinet, then Jules> control cabinet to each drive) Sounds like Massbus connectors... But the docs on bitsavers.org (pdf/dec/disc/RM05) clearly show a separate "adapter" cabinet. My memory isn't good enough to comment further.; Jules> ps. every Linux pdf viewer I can find takes an age to flip Jules> between pages when looking at docs the size of the ones on Jules> bitsavers - to the point that it makes casual reading Jules> completely impossible :-( I noticed that too. Get Adobe's Acrobat Reader for Linux. That one does the job right. Ghostview is pretty decent, too, but acroread is clearly the best. One issue I fought with for a while: acroread was confused about wanting a UTF font and not finding it. (Why not? I have lots of fonts installed...) Anyway, defining "LANG=C" (for acroread, at least, not necessarily globally) fixes that. paul
