RE: HP 28S REF and RREF
thanks for this reply.
still, the 28S is my absolute favourite HP, with a sublime keyboard and feature range, never used the limited graphing capabilities though, for the most part it is great for my Linear Algebra course. I wasn't aware of the 128 K in the 28S, nor that the 48G/GX had 512 K. Did the 48S/SX have REF/RREF functions, and also 512 K ROM? I always assumed the S/SX and G/GX had very similar functionaity... HP-28S (1988 US model), DM41X (2020) |
