Don't forget that Marty's note mentioned the word "miss" in conjunction with "RPS" An RPS miss meant that the disk had rotated so that the next record to be read was past the heads so that there was a wait until it came back around. That was the performance issue he was talking about, and it was a big deal in those days. The maximum rotational speed of a disk was about 3600 rpm.

Marty asked: "RPS miss (show of hands: who remembers what that was?)" Not being in the office tomorrow, it's Friday a day early for me. So how 'bout: - Rock Paper Scissors - Revolutions Per Second - Radiation Protection Suit - "Rps Miss Sure Gold" -- from: www.allbreedpedigree.com/rps+miss+sure+gold - "RPS MISS TRAVELER 905 is a deep sided, big volume, great uddered ..." - from www.sheridanauctionservice.com/auc_files.php?pfid=539 - "Top Open Heifer: Lot 138-RPS Miss Freedom 506" -- from www.angusproductions.com/api_salering2.html?EventID=8407 - and a few YouTube instances which will remain unlisted. And yes, I do remember RPS and RPS misses. And spending uncounted hours organizing OS sysres and other high-activity DASD so that the highest access datasets straddled the VTOC at the center of the volume. I prefer cached the controllers of nowadays, thank you! :-) Happy Friday!
