Figure 4 - Apple IIc Motherboard
Touch the disk drive housing. Remove the Rocketchip from the protective package. Look at Figure 4 and install the Rocketchip in the motherboard socket as shown. Please notice that RocketChip Pin *1 is marked and that all of the part number markings for devices on the motherboard and the Rocketchip are readable and oriented the same way. Before pushing RocketChip fully into the socket, make sure that Pin *1 is oriented correctly and that all 40 pins of the RocketChip are properly aligned in the socket and that they are not bent.
STEP #4: Replacing the Apple IIc Keyboard and Cover.
Gently unfold the keyboard and place it back into position, making sure that the keyboard tabs are inserted in the slots in the disk drive housing. Replace the top cover and engage the plastic latches. Turn the computer over and replace the six bottom screws that you removed in Step #1.
STEP #5: System Check
Turn on the system power. The monitor screen will be cleared and within 2 seconds you will receive the system prompt and a beep. If you do not get the beep, or if the screen has a checkboard, or if the screen is full of “garbage characterS”, then RocketChip is not properly installed. IMMEDIATELY TURN THE POWER OFF, otherwise RocketChip could be damaged. Please review the installation instructions and make sure that all of the pins are OK and that RocketChip is installed in the correct socket and that Pin #1 is correctly located.
