Logic Board Identification (2/98)
 
Issue:
 
 There are two logic boards with ROM version 3 that 
could be used in the PowerBook 1400, 117MHz and the 
PowerBook 1400, 133 MHz units. Because dealers must 
return the same part they ordered to receive 
reimbursement, it is important to properly identify the 
logic board before ordering a replacement.
Part Number 661-1188 has ROM U3 (Low, 341S0203) 
and ROM U4 (High, 341S0204). It works in PowerBook 
1400, 117 MHz and 133 MHz units.
Part number 661-1381 has ROM U3 (Low, 341S0364) 
and ROM U4 (High, 341S0365). It works in PowerBook 
1400, 117 MHz, 133 MHz, and 166 MHz units.
You may receive a 661-1381 logic board as a replacement 
for a 661-1188 if that is the board currently in service
