HP-87

The HP-87 combined the Series 80 architecture with a larger 80-column built-in display and expanded memory capability. It retained the integrated style of the HP-85 while supporting more professional applications.

It was the high-end all-in-one member of the original Series 80 family.

Notable Features

• The larger display supported 80-column text and improved graphics.
• HP-IB provided access to extensive disk, printer and instrument peripherals.

Historical Significance

• It was the high-end all-in-one member of the original Series 80 family.

Collector’s Notes

• Original HP manuals, peripherals and software media are particularly useful because many interfaces and formats were proprietary.
• Memory, storage, displays and expansion hardware should be documented because configurations often changed during a system’s working life.
