I just received my copy of the HP 48 Handbook, by James Donnelly. Donnelly, a software engineer at HP Corvallis, helped develop the HP 28, for which he published a reference booklet. More recently, he was a member of the team that developed the Solve Equation library. This 193 page reference is typeset and printed on good quality paper, coil bound in 5 by 7 inch vertical format. The cover features a full colour picture of the calculator with a beam analysis diagram in its display. The table of contents on the back cover is reproduced below. Introduction 1 Objects, Names, and Constants 3 Memory Organization 15 Graphics 21 Statistics Data 27 Data Transfer 29 Menus 40 User Keys 43 Programming 45 HP Solve Equation Library 64 System Operations 96 Printer Control 101 Built-In Units 103 Messages 110 Menu Numbers 117 Character Codes 118 Object Types 120 Flags 121 Subject Index 125 Command Reference 139 Alpha Keyboard 195 This reference is the only manual you will want to carry with your HP 48. It costs $20 at EduCALC or can be ordered directly from the publisher: Armstrong Publishing Company 3135 NW Ashwood Drive Corvallis, OR 97330 USA I can only agree with the enthusiastic reviews posted by Messrs. Schwartz and Mier-Jedrzejowicz (MEER-yanJAYovitch). A great deal of hard work has obviously gone into making this handbook clear, concise, and accurate. We should all thank Hewlett-Packard for supporting this kind of effort by its employees.
