If you just want to teach assembly (assuming this includes the datapath/control units, the CPU pipeline, hazards, etc) today, you can't go wrong with Patterson and Hennessy's Computer Organisation and Design. Pick your version: MIPS[1], ARM[2], or RISC-V[3].

There's really no need to delve into hardware when teaching assembly, as software simulators/interpreters exist; there's QtSPIM[4], a LEGv8 simulator from ARM itself[5], and a RISC-V interpreter by Cornell[6].

Originally MIPS (or DLX) was the dominant architecture used for teaching computer architecture because the standard Computer Architecture textbook (by one of the main designers of MIPS, David Patterson [1] along with John L. Hennessy [2]) was used in most universities [3]. These two authors were basically the university-lead designers of the RISC philosophy. Patterson's team designed the RISC-I and RISC-II processors (Berkeley RISC [4]). Hennessy and his team designed the MIPS processors (Stanford MIPS [5]). This culmination eventually begot the RISC-V. So yeah, the RISC-V is now the dominant architecture used for teaching computer architecture as they now use RISC-V to teach computer architecture with their latest book edition [6]. Also for more information on that, read [7].
