Okay, I'm going to air a gripe about cisco in this respect.  I'm being
told I should upgrade to the CSC/3 processor card because it has
more memory, the implication is that soon the 1 megabyte in the older
cards won't be enough.  At an upgrade price of $4500, I am paying about
$1500 per megabyte for these three extra megabytes.  This is bad enough,
but if this truly is the "decade of ISO" and ISO routes on a per-host
basis (didn't they learn anything from DECNET?), then how soon will
it be before 4 megabytes isn't enough?  And what will I have to do then,
upgrade to the CSC/4?  

I think cisco should immediately re-engineer the CSC/3 board to allow
addition of memory (perhaps even on a separate card connected by
ribbon cable) *without* having to replace the processor card.  You
can call this the CSC/3+ or CSC/4 or whatever, but you should do this
immediately and offer to exchange existing CSC/3 cards for the new
ones on the most generous terms you can afford.

Look at it this way:  if you don't provide for adding memory, you are
going to have to deal with me and a bunch of other customers demanding
special software builds with only the protocols we need to save space.
If you do solve the problem, you will deal with the same customers by
selling them expansion memory boards.  Which business would you rather
be in?
