This is the must-have companion to slip in the case with your HP 42S Scientific Calculator.

20 pages of condensed reference information covering basic operation to programming. See photo for a table of contents.

Published in 1988 simultaneous to the launch of the 42S, this guide was developed by the author of the original HP-42S User's Manual to be the perfect go-anywhere reminder of all the commands, flags and menus.

Guide is sized to fit perfectly in the slip case alongside the calculator.  

HP liked it so much that they gave it an HP part number and sold it direct to customers as a calculator accessory.  HP part number 92222E. 

Swiss Micro DM42 calculator owners have indicated this guide is also very useful for use with that non-HP calculator, as it emulates the original HP-42S.  Note: the seller does not have a DM42 calculator and has not verified accuracy or completeness with that product.

Free shipping (via USPS First Class mail) to US Addresses only.   

International buyers pay international mailing costs calculated at checkout ($1.50 USD for the first guide; $1.00 for each additional guide). USPS First Class mail does not provide tracking information.
