In those days not too many Computers allowed 1GB Ram. Todays 
clipper 2 will allow 8GB per disk (16 dimm slots, if 1GB dimms 
were supported 16GB were possible) that could be combined by a 
Raid controller.

IIRC the clipper had a battery to keep memory for more than 12 
hours. Other manufacturers have a backupdisk included, I suppose 
in case of a power outage (either power failure or a shutdown of 
the host) the SSD would be backed up to disk. A system where 
such a device was used is supposed to run 24x7.
