The HP 38G (F1200A, F1892A) is a programmable
graphing calculator by
Hewlett-Packard
The Hewlett-Packard Company, commonly shortened to Hewlett-Packard ( ) or HP, was an American multinational information technology company headquartered in Palo Alto, California. HP developed and provided a wide variety of hardware components ...
(HP). It was introduced in 1995 with a
suggested retail price
The list price, also known as the manufacturer's suggested retail price (MSRP), or the recommended retail price (RRP), or the suggested retail price (SRP) of a product is the price at which its manufacturer notionally recommends that a retailer ...
of US$80. HP credits a committee of eight high school,
community college, and university teachers with assisting in the design of the calculator.
The calculator is derived from and the
hardware is based on the more powerful science/engineering oriented
HP 48 series of machines.
Unlike the HP 48 series, which offered both
reverse Polish notation and algebraic entry logic, the HP 38G has only algebraic entry. The calculator is programmable, supporting small, interactive applications called "aplets".
Successors
After a HP 38G+
prototype was cancelled in 1998, the 38G was replaced in 2000 by the
HP 39G and (in Europe and some other markets)
HP 40G. The two models were differentiated by the inclusion of a
computer algebra system (CAS) in the HP 40G. An unofficial method of operating the 40G's CAS on the 39G was addressed in the next follow-up device, the

Beginning with the 39g+, all of these successors have been built using an

CPU with varying degrees of emulation to support software written for previous members of the series, and have gradually added more modern methods of connectivity such as
USB to either replace or supplement the original
RS-232 and
IR.
