Major Assemblies
Figure 2-10 shows a typical 3B2/1000 computer. The 3B2/1000 is available in three different
models: 60, 70, and 80. Each model is slightly different in its configuration.
However, each 3B2/1000 computer is equipped with a "smart" power supply so there is no
noticeable difference in the domestic and international versions. The major assemblies include the
following:
• Power Supply Unit (ACS782A-O)
