If I remember correctly
the 3370 was CKD
the 3375 was FBA
and the 3380 was back to CKD
and the 3390 changed the bytes per track but stayed CKD
all required conversion to move from or to.

We've just been honoring the 3390 all these years by trying to do things
they would have done them. Had FBA been more popular at the time of the
real 3390's, we might be seeing 3350 mod 81's instead.
Had MVS been able to cope with FBA, rather. FBA was plenty popular with the
non-MVS crowd. Also, wasn't 3350 CKD? 3370 was FBA, but I thought there was
one earlier that was at least pseudo-FBA.
