This item has been unavailable for some time from HP, but we have second-hand copies when listed. When we don't have second-hand copies, we have copies of the manual, nicely bound in a spiral binding.
HP48S/SX User Manual. If you lost your manual or never had one, this is what you need. Sometimes we have only one of the two-manual set, which will be noted.
Some editions come in two volumes, and some come as pictured in a single volume. We will receive the full set, whether in one or two separate volumes. Since the HP 48G Series Advanced User's Reference Manual is no longer available, we recommend purchasing this manual as a next-best replacement. There is overlapping content between them.
