Nice job, Apple. I find it kind of inexcusable that they don't have a warning in huge letters somewhere obvious in the documentation for ADB machines. I knew that the ADB was dangerous, so I've never done that to my IIx, but it was nowhere that I read in the docs. I wonder if they plan to make this a bit more robust? Considering the design of the machine, it's really easy to accidentally unplug an ADB device (especialy with third-party keyboards like my Mac-101 with the ADB on the back edge). Pull the keyboard too far away from the machine, and PING! Bye, bye motherboard. --Mike
