>You can get swappable sockets for them. Was looking at the possibility of this for repairing a cyberstorm in the past - allow swapping the cplds to find the faulty one.

Needless to say the price put me off. (and the footprint was too large anyway). Useful for programming/testing qfp chips though...

I've seen similar sockets for BGAs, but they too were far too costly to justify (unless used for testing purposes).

Edit - First price quote in on 68EC060RC75 and I am dumbfounded.
US BID will supply me 3Mhz Hitachi HD63C09EPs for less than $13, but they quoted me $400 for the '060.

Seems a little steep.
I'll have to look elsewhere.
