INTRODUCTION
------------

In this distribution, Computer Computer Corporation provides most of the
information necessary to build the Itsy pocket computer version 1.5.  This
distribution includes the documentation, the schematics (including net-list),
the PLD programming data, the PCB manufacturing data, the PCB assembly data
(including bill-of-materials), and the case manufacturing data.  Most of the
components for Itsy are commercial off-the-shelf components.  However a few
components, in particular the LCD, touch-screen and case, are not
commercially available.

The material in this distribution is provided by Computer Computer
Corporation for non-commercial use only, under the terms of the "Hardware
License Agreement."
