  I also recall that the processor in question at one
point in its
 lifespan, actually used the AM2901 family of bit-slice processors. 
DEC didn't use 2901's in central processors, but the FPU's for 11/34 and
11/44 used 16 of them to make the 64 bit data path for the FPU. They were
also used in some peripherals like the KMC-11.

A lot of OEM's (like Emulex) used them in disk/tape/terminal controllers.
