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.
