LC 475 and Performa 475 models are like the Quadra 605 -- it's a socketed
CPU. Pry very gently with a flathead screwdriver, work your way around the
socket and move it only a bit each time, and it will come out. It might be a
bit stiff at first, but just take your time and you'll be fine. Trying to
find a 68040 chip puller is just going to frustrate you and waste plenty of
time -- I called all around the country looking for one, googled for a few
days and didn't find anything, but found a helpful tech out in California
who told me that taking your time with a screwdriver is the key to getting
it out and not damaging the mainboard. Only solid leads I found about a
68040 chip puller is that they were included in Apple's 601 PPC upgrade kit
and the QuadDoubler upgrade (manufacturer on that one evades me at the
moment -- Sonnett? Presto?). The lowendmac.com swap list is a great place to
find one -- might try asking for dead Quadra mainboards with good CPUs.

You'd be best off removing the LC040 and replacing it with a real
040. Provided your processor is socketed (I don't recall whether or
not that's the case in the 475, but popping open the case will
answer that question for you) or soldered. In the latter case,
you'll have a hard time replacing the processor. Based on another
post, though, it sounds like you're okay.
