As a general rule, if the Power Macintosh 7200/90 computer has 

a serial number of xx545xxxxxx or higher, then the computer 

should have the revised logic board already installed. If the 

computer has a serial number of xx544xxxxxx, xx543xxxxxx or 

below, verify that the board is revised as follows:

Look at location G1; G1 is located next to the internal 50-pin SCSI 

connector and the CURIO ASIC.

•  If a 20 MHz oscillator is present at location G1, the logic 

board has been revised.

•  If a 20 MHz oscillator is not present (four blank solder 

pads) then the board has not been revised and should be 

replaced under warranty.
