Your Hewlett-Packard 85 Personal Computer is a versatile, self-contained, personal
computing device which enables you to preform a wide variety of useful and
interesting functions. To mention just a few of the special features of your
HP-85, you have the ability to:
|
|
|
|
|
|
|
Perform calculations in a simple, straightforward manner—as if you had a
calculator with dozens of mathematical and scientific functions.
|
|
|
|
|
|
|
Compose programs in BASIC (Beginner’s All-Purpose Symbolic Instruction Code)
programming language. The HP-85 exceeds the latest American National Standard for
Minimal BASIC. In many areas, the HP-85 includes enhancements to this standard.
The built-in RAM (random access memory) to store your programs is 32K bytes
(32,768 characters of information).
|
|
|
|
|
|
|
Execute BASIC programs. After you have written your programs, they may be executed,
often at the touch of one key. The HP-85 offers several typing aids to your
program execution and control.
|
|
|
|
|
|
|
Load and store programs and data on magnetic tape cartridge with the
built-in tape drive. Thus you may permanently store your programs to
be retrieved again, whenever you wish.
|
|
|
|
|
|
|
Use the high-speed storage capacity of the built-in electronic disc, which initially
holds 32K bytes of programs and data, expandable up to 544K bytes.
|
|
|
|
|
|
|
List programs and data with the built-in thermal printer. Not only can you
list programs, but you can copy anything that appears on the display onto the printer,
to record and review your results.
|
|
|
|
|
|
|
Perform graphics. The graphics capabilities of the HP-85 are sophisticated, yet
easy to use. And again, anything that you can ‘‘draw’’ on the
display can be transformed to hard copy with a single command: COPY.
|
|
|
|
|
|
|
Edit, correct, and modify anything that appears on the display with tremendous
ease. In fact, the HP-85 allows you to access and review 64 lines of characters on the
display, and to edit them at your convenience.
|
|
|
|
|
|
|
Use the HP-85B with plug-in ROMs (read-only memories) to control a variety of
Hewlett-Packard peripherals, including disc drives, printers, plotters, and instruments.
