The HP-27S was a
pocket
calculator
produced by
Hewlett-Packard
, introduced in 1988, and discontinued between 1990 and 1993 (sources vary). It was the first HP
scientific calculator
to use algebraic entry instead of
RPN
, and though it was labelled
scientific
, it also included features associated with specialised business calculators.
The device features standard scientific functions, including
statistics
and
probability
. Equations could be stored in memory, and solved and
integrated
for specified variables.
Binary
,
octal
, and
hexadecimal
number bases could be used. Business features included a
real
-
time clock
and
calendar
with up to ten appointments (each with a 22 character message string), as well as functions such as
time
value
of
money calculations.
The calculator has 6900 bytes of usable memory, shared among variables and formulas. Ten storage registers R0 through R9 could each hold one number.
Its hardware features included a
dot-matrix display
of two rows of 22 characters. Depending on context, either the top row was used to display the current expression or a message, or the bottom row was used to show menu options, which could be selected with the corresponding keys. An infra-red transmitter was also included, allowing the machine to be used with a compatible printer, such as the HP 82240B. A beeper could be used to sound date/time alarms.
The 27S was not
programmable
in the conventional way, but it included an advanced formula-storage system with programming features. Within stored formulas, sub-formulas could be defined and later referred to by name. Loops and conditional execution could also be embedded within formulas.
