Note: This version of the manual applies to version 1.5 of Power48.

Introduction
Power48 is a PalmOS based emulator for the Hewlett-Packard 48SX, 48GX and 49G
series of calculators. It provides a fairly complete emulation of the Saturn CPU upon
which these calculators are based and is able to run a majority of the programs
available for them.It emulates one instance each of the 48SX, 48GX and 49G, and
maintains complete and separate state information for each allowing the user to quickly
switch between either one.
Power48 is based primarily on Emu48 originally written by Sebastien Carlier and now
maintained and updated by Christoph Gießelink. It is important to note however that
Power48 is not 100% equivalent to Emu48, asstate and port files generated by Emu48
are not compatible with Power48 and vice-versa. Additionally, the core emulation code
has been almost completely rewritten and optimized for the Palm platform in an attempt
to squeeze in every ounce of performance possible.
Power48 requires the presence of a ROM image for each target (48SX, 48GX, and
49G) that the user wishes to emulate. These ROMimages are the property of and
copyrighted by Hewlett-Packard and are not distributed with this emulator. Please see
the installation for directions on obtaining ROM images and how to install them.
