General Information - HP 9100B Operating & Programming Manual

GENERAL INFORMATIO
This section contains general information about the Model
91008, its accessones, servicing information, etc. Also in·
cluded is the turn-on procedure and a method for checking
the performance of your calculator.
Your Hewlett-Packard 91008 Calculator is an easy-to-use, yet
scientific, desk-top calculator. lt is capable of performing
operations ranging from the very simple to the very complex,
such as are encountered in business, educational, scientific
and engineering problems. Trigonometrie, logarithmic and
mathematical functions are performed with single key strokes.
The 91008 is also programmable: its computer-like memory
enables the calculator to store instructions and data for repet1·
tive and iterative solutions. Conditional branching (which allows
the calculator to automatically make decisions while performing
a program) and the use of subroutines provides complete pro-
gramming capability. Knowledge of special 'machine language'
is not required in order to program your calculator.
Programs can be recorded on the magnetic cards supplied with
the calculator. Recorded programs can be reinserted into the
calculator at a later date, thu s eliminating repetition of the
time-consuming step-by-step entry. A pull-out instruction card
is located, at the front of your calculator, below the keyboard;
the operation of each key is briefly explained on this card.
