Someone asked me the following question: 

	Where did the speeds for records come from?
		(78 rpm, 45 rpm, 33 1/3 rpm)

I had no idea so I thought I'd ask the net.  Incidentally, the
questioner observed that 33 + 45 = 78.  (Yea I know it's 33 1/3...)
This latter point strikes me as coincidence...

If you have any information or comments on these two points,
please let me know.
