Still half a sleep, but my yellow card , GX20-1850-3 lists, I think 132 non-float point instructions in total of which 34 are marked as privledged. I also have 51 floating point instructions. As usual these numbers are not exact as some instructions are not implemented on all models and its early so my counting might be out:-(
