Since we at HP may have inadvertently started the latest frenzy of version speculation, it seems appropriate for me to put an end to it: THERE ARE NO VERSION F HP48SX ROM's IN EXISTENCE ANYWHERE, AND HENCE NO HP 48SX CALCULATORS LATER THAN VERSION E. This unequivocal statement does not imply that there will or will not ever be a new 48 ROM version. How did the most recent rumor get started? Well, whenever we release a ROM version, we routinely increment the version letter by one in the simulator versions we use here at HP. This helps us keep track of experimental versions, and distinguish them and any associated software from the released versions. It happens that the PDL transfer library was developed on a simulator, and we simply overlooked the fact that it has a version F header which might set off sirens in the user community. The library will work perfectly well on any version HP 48--in case you haven't noticed, all 48 software works on all 48 versions (at least I've never heard of any that doesn't, not counting the effects of explicit bug fixes).
