The following text appeared on page 43 of the August 1980 edition of Byte magazine, as the message in a Hewlett Packard advertisement:

Imagine the new world that would unfold before you if you had a powerful, portable, completely integrated computer system at your personal disposal. And at an affordable price. That's exactly what Hewlett-Packard has just created.

At the lab, on your desk or in your study this 20-pound, self-contained system provides professional computing power when and where you need it. That means no more waiting for data to be remotely processed and returned.

You get all this in the HP-85:

Interactive graphics under keyboard control.

16K RAM Memory standard.

Standard typewriter keyboard with separate numeric keypad and eight user-definable special function keys.

High resolution CRT display with powerful editing capability.

Built-in thermal printer produces a hardcopy of the display on command.

Built-in tape cartridge drive. Each cartridge provides 217K bytes of storage capacity.

Operating system and BASIC language, permanently stored in ROM.

Hewlett-Packard has combined these sophisticated capabilites with advanced design to give you a system that is easy to use yet uncompromised in its power.

A key to this achievement is Hewlett-Packard's choice of BASIC for the HP-85's language. The HP-85 has more than 150 commands and statements to let you solve your problems swiftly and easily.

In addition, sixteen graphic commands have been added to the HP-85's extended BASIC to give you easy control of its amazingly versatile graphic capabilities.

Whether your in science, engineering, industry or business, the HP-85 you need today can easily be expanded or customized to meet you needs tomorrow.

You can double RAM capacity to 32K or expand ROM firmware to 80K with optional modules that plug right into the HP-85.

You can enhance the system's capability by adding powerful HP peripherals like high-speed, full-width line printer, full-size plotter, or flexible disc drives.

And HP Application Pacs offer preprogrammed solutions in a wide variety of disciplines on prerecorded magnetic tape cartridges.

So, when you buy the HP-85, your not just buying a computer system, your buying the confidence that the Hewlett-Packard name brings and the knowledge that the HP-85 can expand with your changing needs.
