Yes and no. There are separate manuals for the EAE (links here:
https://gunkies.org/wiki/KE11-A_Extended_Arithmetic_Element
https://gunkies.org/wiki/KE11-B_Extended_Arithmetic_Element
the -B is the same to program as the -A; its implementation is just a single
board, though) but the -11/20 processor handbook (the second version; the one
dated 1972) does have a chapter (Chapter 8; Part I) on the EAE.
(For no reason I can understand, neither the -11/05 nor the -11/04 processor
handbook covers the EAE, even though neither one has the EIS, and if you need
multiply/etc in hardware on either one, the EAE is your only choice).
