The Extensa 67x notebook series is similar in construction and appearance, has similar operating controls and indicators and uses the same software. It uses a similar startup self test program (described in detail in Chapter 5 of this manual). There are differences at the board level which affect assembly/disassembly as described in Chapter 6 of this manual. There are also differences in Field-Replaceable Units (FRUs), particularly the Printed Circuit Boards, so separate FRU lists and logic diagram sets are provided in the appendices. Table 1-1 summarizes some of the major differences between the 67x Series and the 65x Series Notebook Computers.
