Yes, I have a few 'san francisco special' ungrounded power tails but to my knowledge they were only made during the PowerPC era and did not continue into the Intel era.

e. oh grounded short adapters. I wouldn't go for that due to the wall wort issue. I usually swapped out my apple bricks to grounded tails because it was usually easier to work into whateve ad-hoc power I encountered.
