IBM had DASD (anyone pronouce it?); CDC had RMS.
Crossing between
the two cultures could be very confusing.
I say "dazzdee". I've never heard anyone say "Dee Ay Ess
Dee".
It's mostly been Dazz Dee for me;
however, occasionally I have heard or said Dee Ay Ess Dee
How about IBM's CKD - always "See Kay Dee"?
Most people I've heard say "see kay dee", but some people have said
"sicd" as in "he sicd the dog on me".
