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