The 3480 is not a difficult piece of hardware to install, but it does require more
planning than some new products. This is due, in part, to the fact that tape tech
nology has not changed for a very long time. There may not be much expertise
within your data processing shop on the subject of tape conversions.
It is our intent to discuss the things that the reader will need to know to complete
a 3480 conversion. A lot of the discussion will provide background material for
the 3480. Given this information, the reader should feel comfortable about devel
oping a conversion plan and executing it successfully.
Much of the information in the first edition of this manual was learned from the
3480 A22/B22 Early Support Program (ESP) accounts who had to work through
this plaiming process without benefit of the type of information presented here.
This Bulletin can be read front-to-back or used as a reference. Some material is
previously published, sometimes in another form, while other material is available
for the first time. We assume that the reader has some general knowledge of tape
In addition to the material in the original Bulletin, this version contains informa
tion on the 3480 model All/Bll subsystem, the Automatic Cartridge Loader
(ACL), and the increased storage for the A22 buffer. We also revised the VM
Support section in Chapter 4 so that it is more informative and useful, and added
the VSE Software support section.
