Rev. B, 5000 Series
 
Apple introduced an updated 5000 series version several 
months after introduction. Referred to in this manual as 
“Rev. B,” the updated version incorporates design changes 
that are not backward-compatible. Models in the 5500 
series are made entirely with Rev. B parts.
To determine which version you are servicing, remove the 
front bezel and note the location of the speakers. If the 
speakers are part of the front bezel, the unit is the original 
version. To service the original version, follow the manual 
for take-apart procedures and parts information, unless the 
procedures specify Rev. B.
If the speakers are attached to the sides of the metal chassis, 
the unit is Rev. B. To service Rev. B models, follow the 
manual, substituting Rev. B procedures and parts.
