Hm.  I remember some RC25s on RSTS, and they seemed to be ok.  The fact that 
they had two drives on one motor made it strange, especially if the fixed 
platter was your system device.  We had to teach the OS how to deal with SY: 
going away temporarily.

It did make for nice compact systems, which was important when we got an order 
for a pile of RSTS systems that would be installed on board submarines.  Or so 
we were told.
