HP and Tek both made ultra-micro grabbers for use with logic analyzers. I've got a few for the Tek 9100/1240 series analyzers. They have an anodized or painted metal tube with two springy wires in it. The wires have bends right at the end, and the button extends the wires, opening up the grabber. You might check eBay under logic analyzer accessories or the like. The one you link to looks just a little different, but I think is somewhat similar. Jon
Re: source for smt probe clip
I've got lots and lots in HP probe kits. Just gota brand new HP probe kit for #40 with some 80 clips and 4 "Hydra" termination cables.

Setup of the scan is easy, the chip has clear, load and shift. On each pass, clear the chain, load a 1 on the serial input then shift to probe the other 40 pins. Step and repeat. This is simple enough the whole thing should be able to be bit banged by an FTDI UM245R Software is then pretty simple. Display a .1" grid of points (41x67) and each single-pin probe sweep is a net. Light the hits so you don't bother scanning points that are already in a net. Start with power and ground. An added benefit is you'll pick up the DIP, power and ground connections to all the passives, as well as all of the vias in the net and connections to the IBM cans that you can't probe from the top.

I bought 100 of the Tektronix ones a few years ago. They work fine but can be easily damaged if your not careful.

Re: source for smt probe clip
EZ-Hook XKM. I don't know whether they cloned the HP grabber probe, or supplied them to HP. They're expensive, so I usually buy the HP grabbers on eBay. Watch out. There are some Chinese clone grabbers that look like the XKM or HP, but aren't nearly as good.

Has anyone seen a source for these clips? http://bitsavers.org/mysteries/salea_clip.JPG They come with the Salae logic analyzer, and are like the HP logic analyzer clips in that the wire is detachable, instead of the common style you can buy where you have to solder on a wire.
