The article has a section on the origination of RISC-V, but never mentions RISC-I through IV: "RISC-V is the eponymous fifth generation of his long series of cooperative RISC-based research projects at the University of California, Berkeley (RISC-I and RISC-II published in 1981 by Patterson, who refers[21] to the SOAR architecture[22] from 1984 as "RISC-III" and the SPUR architecture[23] from 1988 as "RISC-IV"). At this stage, students provided initial software, simulations, and CPU designs." https://en.wikipedia.org/wiki/RISC-V https://en.wikipedia.org/wiki/RISC-V
