The PDP-8 had seven OPCODES, not seven instructions.  Two of them,
OPR and IOT were microcoded, and so it had many more instructions than
that.  By the above logic all RISC machines have only one instruction because
the instructions are, after all, just microcoded words.

As a humorous aside, judicious use of the OPR microcde on some of the PDP-8
machines, could even generate a  CISCy "set accumulator to 2" instruction =

This worked on a PDP8/S in run mode, but, oddly enough, not in single step. I
never tried it on the other PDP-8 flavors.
