During
its manufacturing time the LED-display of the first SR-11
was revised from the original 6-digit modules to 12 discrete modules. We know
the same step from the SR-10 Version 1 to the later SR-10
Version 2.
Everything
else kept unchanged and therefore the
inside view of the SR-10 and its successor SR-11 still look very similar. Please
compare them
yourself.
Press the X-RAY button and view the
internals of a late SR-11.
