A few months ago I was using an Open Bench Logic Sniffer v1.04 from Dangerous Prototypes to decipher a problem with an SD card controller. It sure was nice to have a $50 device that works at least as well as the $5k devices I used in the 80s, and the performance is perhaps a hundred times greater than the tools I used with Intel and Motorola processors in the datacomm devices we created at Network Products.
