When I recovered the Foxboro Fox 2 and waterlogged 11/05 on my recent road trip, I was lucky to
find an original 11/05 print set dated 1973. For what it's worth, the microcode listing in my doc
is Revision B and it is *exactly* the same printout as in the the Bitsavers doc Revision C except
it is more legible and has fewer splotches and spots on it. The only other difference I can see
is the Rev C listing has the 'digital' logo added to the page edges.

By the way the above pdf is missing a page that is in my set, namely to do with the 5-1/4" height
power supply (H726-B) pictures, as well as some other pages of the chassis, possibly more but I
haven't gone through it that closely.
