b) EPROM (red) containing the new operating system for the EX version of these instruments.
c) i2/i3 HDisk board

e) Hard disk with attachment strips.
f) Mounting accessories (2 spacer bolts, 2 screws, 1 cable strap)
1. General
The room in which the components are installed must be clean and dry. Note that there are delicate
electronic components inside the i2/i3, which could be destroyed by electrostatic discharge. For this
reason you should avoid touching the components' contacts.
The only tool required for installation is a Phillips screwdriver.
2. Data Back-up
Before you begin with the installation, use the "SAVE ALL DATA" function of the "DISK" menu to make
a back-up copy of all the i2/i3 data to floppy disk or via MIDI to another MIDI device!
3. Opening the i2/i3 Keyboard
Switch off the instrument and disconnect all connecting cables, especially the power cord of the
keyboard.
Turn the keyboard upside down (please mind the joystick!) and unscrew all the screws which are
marked with an arrow in illustration 1. Turn the keyboard over again and fold up the complete front
panel. The "Main Board" (main control board) of the i2/i3 will become visible (illustration 2).
4. Exchanging the Operating System
IC29 which contains the operating system of your i2/i3 is marked with an arrow in illustration 2. Lift
IC29 off its socket and replace it with the new operating system EPROM supplied (the yellow
EPROM is for "normal" devices and the red EPROM is for EX version devices!). Pay special attention
to the polarity of the chip (the "nose" must be pointing to the left!).
