Don't need full PCI capture, full state analysis, or anything like that: being able to look at peripheral buses, e.g. a CFI flash parallel bus, LPC, ISA, i2c, and/or 10/100Mbit MDIO interfaces would be most useful. This guy has covered some of the grabber bases, however being able to get at really small arbitrary layouts e.g. with miniature pogo pins would be even better: http://www.knjn.com/ShopCablesProbing.html I see a lot of Chinese USB2 based stuff popping up on eBay. Trouble is of course, they require Windows, and they don't have grabbers I can easily attach to hardware with the probe cables. Trouble with MiniLA is, whilst the designs are public, no one seems to be manufacturing them. I found Tony Bybell, the maintainer of GTKWave, is responsive and helpful to queries.
