[G4] Orig. peripherals needed?

[Eric Buczynski]

I have a G4 Digital Audio model upgraded to a Sonnet 1.2Ghz G4  
processor.  I also have a Motorola 802.11g PCI card in place of the  
original Airport card.  Do I need to keep these around in case I do a  
brand new installation of Tiger or the next operating system?

The reason I ask is because I had a Powermac 7300 which had a 68040  
daughtercard and that was replaced by  a Sonnet 400mhz G3 chip.  It  
was rare, but when installing a new system on it I'd have to take out  
the G3 upgrade and put in the original daughtercard and some other  
chip (that the 68040 used) to start from scratch. I know that both  
the original processor and the upgraded processor in my current mac  
are both G4 chips, but I don't want to sell the original processor  
then realize down the line when I install a new OS that I need the  
original processor first.  Has anyone encountered this problem before  
or is it ok to sell the older processor and original airport card and  
not worry about needing them for a later OS installation?  I could  
always keep the two for troubleshooting purposes, but my Mac has been  
very reliable compared to the 7300.  Thanks for the tips.
