[TriEmbed] lqfp-100 "proto-clip"?

[Jon Wolfe]

I seem to recall seeing something like that a while back, but they were very, very expensive, like 3 figues expensive.
Ill try to jog the memory. I used to peruse the Mouser hardcopy catalog as a sleep aid, I bet it was in there.

</div>I mis-spoke. I'm not trying to connect an in-circuit emulator to a 
lqfp-100 chip, just a logic analyzer. Being a mechanical doofus of the 
highest order, it seems completely reasonable to me to be able to stick 
something on the top of the package, arrange a few spring-loaded but 
very, very precise little bendy things and get on with it. They might 
need some plastic "accessories" to arrange for sets of them to sit on 
the chip leads while maintaining the proper spacing. Hmm, OK, maybe the 
whole thing would sit on the chip with a square surround that provides  
itty-bitty slot openings over each lead and the adjustable thingum 
swings around and sits on that.
