[78-L] the 'deadest' consumer audio formats?

[Dan Van Landingham]

Regarding cassettes:what about the old type 3 ferrochrome tapes?I owned a few 
about thirty years ago 

courtesy of the local Radio Shack dealer here in North Bend,Oregon.I had used 
some chrome tapes
but I remember little of the sound quality of them.Ferrochrome wasn't around all 
that long as I recall.My
first cassette recorders didn't have the type IV function.My earliest recorder 
was an old,piano keyed 

Hitachi from the '70s a friend gave me.
