The printed manual is getting to be unwieldy. I could see having it split into
two, or possibly three, volumes: the basic hardware design and features, the
privileged instructions, and the unprivileged (and semi-privileged) one, with
Appendix A split (and expanded) accordingly. The digital version is just fine,
except for the skimpy Appendix A.

The major nit I have to pick is with the operand description. After more than
forty years of use, I still manage to mistake R1 for GPR1, etc., and have to
make a conscious effort to read it correctly.
