The 11/35 & 11/40 use the same CPU board set, memory, and I/O boards. The front panel on the 35 & 40 is the same except for the silk screening. All of the 35 & 40 documentation is on Bitsavers: Index of /pdf/dec/pdp11/1140. It uses Unibus for the I/O bus, so you can borrow controller boards from any Unibus machine.
