My KB11-A prints have an 'overall' date of "4/76" (on the front page), but
prints within the set seem to be older.

E.g. my M8100 prints are dated 2/72, and none contain any entries in the
'Revisions' block (lower left). However, they are marked as Rev. D, which is
newer than the KB11-A prints at Bitsaver, which are marked as Rev. C. So I
have no idea what changed to cause the rev update! (The first drawing, the
board layout, does show a listing for 'D', so maybe it was just a layout
change?)

The boards aren't all the same rev, though: the M8102 in mine are marked Rev.
C.

My KT11-D prints are dated "5/72" (on the front page), and the M8107 prints
are hand-marked as Rev. A, but the M8108 pages have mostly been replaced with
'yellow-sheet' updates with Rev. F, dated 6-'73.
