Custom Peatures for
IBM 1401, 1440, and 1460 Data Processing Systems
This manual contains brief descriptions of
some of the custom features available for the
IBM 1401, 1440, or 1460 Data Processing
Systems. Availability of these features can
be determined by requesting a price quota-
tion from IBM.

PREFACE
Custom features are designed to meet special appli-
cation requirements beyond the capabilities of the
standard or special features available with the sys-
tem. These custom features are developed as a re-
sult of the submission of a Request for Price Quota-
tion (RPQ) through an IBM sales representative.
The number assigned to the RPQ when originally
submitted becomes a reference for future requests
for this function.
This brochure lists, alphabetically, the RPQ's
applicable to the IBM 1401 alone (Section 1) and
those applicable to the IBM 1401 or the IBM 1440 or
the IBM 1460 (Section 2). An index is provided by
RPQ number at the end of the publication.
In considering these custom features, give spe-
cial consideration to the prerequisites necessary for
the proper operation of the RPQ. For further de-
tails and advice on custom features, consul t your
IBM sales representative.
Copies of this and other IBM publications can be obtained through IBM Branch Offices.
Address comments concerning the content of this publication to IBM Product Publications, Endicott, New York 13764.
