I would assume from my current understanding ie. that early pioneer series would have used higher priority implicid multiplication. Then with same or other models at some point removed this extra layer used for grouping at paper (at some branches of mathematic). Etc.

I can't confirm for all of the Pioneer models that use algebraic entry but the HP-20S and HP-22S do not support implied multiplication. The HP 35S does support implied multiplication but does not give it priority.
