MEMORY
The ROM chips contain the computer operating instructions. Memory devices are very sensitive to
static charges. Use grounding precautions when handling these parts.
To remove a ROM chip from its socket, carefully note its position and then lift the chip using a chip
extraction tool. To reinstall a ROM, place the chip over its socket so that the notch in the chip lines
up with the silkscreen on the board, and press down firmly to seat. Do not force the chip into the
socket. Do not bend the pins under the chip.
CAUTION
Use wrist straps, conductive mats or other methods of safely discharging static electricity. Hold all
integrated circuits by their packages and not by the metal pins. Extractor and insertion tools are
recommended to avoid bent or broken pins caused by excessive force.
POWER SUPPLY
Unlock and remove the backbox rear door. Unplug the IEC cord and remove the four outer screws
surrounding the power supply that secure it to the case. See the drawing below.
Rear view of the computer case
Unlock and remove the backglass and the translite. Unscrew the two screws on either side of the
power switch. Grasp the computer case from the front and slide it toward you. Let it hang in front of
the backbox, see the drawing below.
Side View of Backbox
Open the top of the computer case. Unplug the cable harnesses leading from the power supply; one
plug is going to one connector on the power amp and two plugs are going to one connector on the
CPU board. Lift the power supply out of the computer case.
NOTICE
Always replace the computer case cover. Failure to do so will void FCC, UL and CE compliance,
and may cause damage to the PC boards in the case. The foam lining of the cover holds the PC
boards securely in place and protects them from vibrations that normally occur in a pinball game.
