HP 27130A
The HP 27130A uses several of the Z-80A family of microprocessor components to relieve the host
computer of much of the overhead. This permits a wide range
of configurable transmission
modes and formats, thus allowing connections to various CRT terminals, printing terminals, printers,
and plotters.

IDENTIFICA TION
The Product
Up to five digits and a letter (2 7130A in this case) are used to identify Hewlett-Packard products.
The five digits identify the product; the letter indicates the revision level of the product.
Printed Circuit Card
The printed circuit card supplied with the HP 27130A product is identified by a part number
marked on the card. In addition to the part number, the card is further identified by a letter and a
four-digit date code (e.g., A;...230l). This designation is placed below the part number. The letter
identifies the version of the etched circuit on the card. The date code (the four digits following
the letter) identifies the electrical characteristics of the card with components mounted. Thus, the
complete part number on the MUX card is:
5061-4929
A-2301
If the date code stamped on the card does not agree with the date code on the title page of this
manual, there are differences between your card and the card described
herein.
These dif-
ferences are described in manual supplements available at the nearest Hewlett-Packard Sales and
Service Office (a list of Hewlett-Packard Sales and Service Offices is contained at the back of this
manual).
