It all became something of farce when there were no longer any real CKD
and real multi-track search ... all being simulated on fixed-block
devices (there hasn't been real CKD manufactured for decades).

traces back to late 70s when MVS wouldn't provide FBA support. Then
E-CKD (sort of minor FBA subset) was introduced for calypso
speed-matching buffer (allowing 3mbyte/sec 3380 disks to be retrofitted
to older machines with 1.5mbyte/sec channels). I would claim that the
pain to get E-CKD and speed matching working was on par if MVS had done
FBA support originally (and speed matching would be fallout of FBA
support) ... and it would have also eliminated the subsequent enormous
costs and overhead associated with continuing to emulate CKD ... even
when CKD hasn't existed for decades.

some of this was recently discussed in ibm-main
