	Does anyone know what the effective speed of the old cylinder
	recordings was (as related to disc RPM speeds).  Knowing how
	some engineering decisions are made, there might be a direct
	relationship with the tangential speed of the cylinders to the
	RPM speed of the 78 RPM discs....

	Those who said that 16 2/3 was the correct speed are in agreement
	with the old advertisements for these "records".  Actually, the
	speed was advertised as a compact disc form for voice recordings.
	Their "compactness" in storing "talking books" was to be the best
	way for the visually impaired to hear the information without
	hiring a relatively expensive reader.  Whole libraries were supposed
	to be made into this "audio microfiche" format for "permanent"
	storage...etc...etc.
