In the schematic I have which is the same as the
one at bitsavers:

E102 / A04A2, E112 / A10A2, E103 / A20A2 and E114 / A11A2.
Are there plenty of different versions of PCB and microcode??

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.
