captive screws	

· Flat blade screwdriver -- for extracting ROM chips

Installing the Firmware

6. Extract the existing ROM chips ( ! ) by sliding the flat blade	
screwdriver underneath each chip and gently loosening the	
pins from their sockets.	

7. Carefully align the pins on each new chip with the sockets on	
the board, noting the orientation of the notch ( " ).	

Note: You may find it easier to align the pins with the sockets	
if you bend in the pins slightly. The pins bend easily, so gently	
rock each chip on its side, on your flat work surface, to adjust	
the pins for alignment.	

Press the chips firmly and evenly to seat them in their sockets.
