When I cannot get the SPI to detect with 3.3v, I've tried 3.v (basically connecting 2 AA batteries to power it), if I can't get a consistent read then I go up to 5v.
I did read something about someone putting together an arduino based spi reader/programmer but they're nowhere near as fast as using a Blackcat/Flashcat or an JTAG NT to read and write back. Alternatively, if you already have one of those random Atmega32U2 boards with all the gpio points on it, you could flash the Blackcat/Flashcat spi hex on it and use that instead.
For clips, I suggest you get the pomona 5252. I've went through several of the 3m clips and found the pomona to have a softer spring on it and the wider base make sit easier to open and close the clip without the risk of bending the pins on it.
Here's the link for the clip: http://www.newark.com/pomona/5252/test-c...=soic+5252
I have one for every one of my programmers.
