1.2 Product Overview
The Extensa 660 Series contains two major product lines including:
¨660 CD Series
¨660 CDT Series
Both notebook series are similar in construction and appearance, have similar operating 
controls and indicators and use the same software. Both notebook series use a similar 
startup self test program and diagnostics program (described in detail in Section 5 of 
this manual).  The two models differ in Hard Drive capacity and LCD screen size as 
listed in Table 1-1 below.
