General Information
Model 743 and Model 744 VME Board Computers
CPU Circuit
The Model 743 uses a Hewlett-Packard PA-RISC 7100-LC CPU chip and the Model 744
uses a Hewlett-Packard PA-RISC PA7300-LC CPU chip. The CPU chip is the heart of the
CPU circuit. It executes instructions and controls the other circuits.
Table 1-7 lists the CPU performance figures of the Model 743 with HP-UX and Table 1-7
lists the CPU performance figures for the Model 744 with HP-UX.
