    Well the CSC3 comes with 3MB of memory.

Grr.  We never should have called it a csc3.  Some people think that means
it has a 68030 processor, and apparently some people thubk it means that it
has 3 meg of memory.  In actuallity, it is just the third processor that
cisco has built.  It has a 30MHz 68020 and 4Mb of memory.

    The software is loaded from EPROM (or your favourite TFTP server) into
    RAM.  I am told that 8.2 will have the option of running it from EPROM. 
    In my eyes a big plus! 

Yes, in the first maintanance release of 8.1 (you don't have to wait for 8.2)
we will run the software directly from ROM.  The slows everything down by a
small fraction (5-10%), but frees up 600K+ of memory.  Shipping NOW, BTW.
