Adding FPU to Color Classic

I'm thinking about adding an FPU (math coporocessor) to my Color Classic out of curiosity. I know that a lot of 86k Macs called for Motorola 68882 chips for this purpose, and a quick search on eBay shows that they're plentiful and cheap (as in $5 shipped). Is there anything I need to look out for when picking one of these up? Obviously it'll need to have the correct form factor (chip carrier), but are there other considerations?

Is there an empty socket for an FPU on a Color Classic?


Edit -- googled it...  yes, there is.  And the pic I found shows a 68882 installed, so that's what you want.  Make sure the clock speed is at least as fast as your CPU.  The one in the pic I found looks like a 33MHz part.
