Changing System Software
The system software is contained in EPROM IC17 on the 2775 Main Board. New software
releases are made available from time-to-time. These new releases may add features or be
maintenance upgrades. To install a new EPROM:
1. Follow the steps listed in
Assembly Exchanges
on page 40 to open the monitor. Be sure to
disconnect J102 from the 2775 Main Board to ensure that there is no power on the board while
changing the system software.
2. Use a PLCC extraction tool to carefully pry the EPROM IC17 from the socket.
3. Install the update EPROM into the socket. Align the EPROM so that IC17 pin-1 is inserted into
pin 1 of the socket.
