Overview of the Conversion Process
1.1 In This Chapter
This chapter describes the general process for upgrading a VAX 4000
Model 100 or Model 100A to a VAX 4000 Model 105A system by replacing
the KA52 CPU module with a KA53 CPU module.
1.2 Overview of the Conversion Processes
Tasks required to upgrade VAX 4000 models are summarized below. To begin
the actual conversion, turn to Chapter 2 for the conversion of a VAX 4000
Model 100, or Chapter 3 for the conversion of a VAX 4000 Model 100A.
The VAX 4000 Model 100A is identical to the VAX 4000 Model 100, except that
the port cover is designed to accomodate a dual DSSI port.
The conversion of a VAX 4000 Model 100A to Model 105A involves replacing
the CPU module and the system medallion. These procedures are described in
detail in Chapter 3.
The conversion of a VAX 4000 Model 100 to Model 105A includes upgrading
with a new port cover (as if it were being converted first to a Model 100A),
then replacing the CPU module and the system medallion. These procedures
are described in detail in Chapter 2.
