Hi, I just recently purchased my first Mac, a Performa 630CD (AKA Quadra 
630) for the princely sum of 53 dollars. I've done a fair bit of research 
into vintage Macs before I bought one but there's still some questions I 
haven't found answers to.

1. I haven't opened my Performa up yet, but chances are it still has the 
original 68LC040 and I didn't get lucky by buying one with a proper 040 
upgrade. I've found decently priced 040 chips on eBay but they're all 25MHz 
chips, which would be slower than the 33MHz LC that's (probably) already in 
there. Would a 25MHz 040 installed in a motherboard with a 33MHz clock 
crystal run at 33MHz or is 25MHz the maximum speed it's capable of?

2. I've heard the SCSI controller in the 630 is absolutely abominable due 
to being slow and outdated. Can it be replaced with a more modern 
controller from another Macintosh?

I appreciate hearing from some people with more Mac experience than I have.
