We are able to probe 208-PQFP's with with very small clips from Emulation
Technology, Inc. They also have adapters which provide an ordinary square
post for every pin of such a large chip. In my experience, both are some
trouble to use; but it may be inevitable for such a fine pitch. The small 
clips are on page 110 of their 1996 Interconnect Solutions catalog.

Their phone number is 408-982-0660, fax 408-982-0664
