I supsect that the Sony  SMC-70 may have been among the first systems to 
come out with the  things.

Fortunately, I still have several cartons (duplicator grade) of  blank 
DSDD 3.5" mdedia.  A few months ago, I gave away (FFS) about  1,000 of 
the things.

I suspect that the the world's supply is far  from exhausted.  Lots of 
common word processors also used them (e.g.  Brother).
