The University of Missouri, Rolla 9 drive 2314 was hydraulic, and on 
night a drive's actuator unloaded into the pack area, and took it out, 
but the damage from that major failure was contained w/o the pack or 
actuators exiting the enclosure.  however the debris took out all the 
packs and drives.

IBM had to air freight in an entire subsystem to replace it.  The 
datacenter was down for about a week.  Main system was a 360/50 MVT / 
HASP system FWIW.

This 1800 would be a great system to preserve and eventually restore.

I agree with Jon, hard to tell how to actually run these disks now days.

(BTW, Jon and I are from UMR)
