OK, I'm confused.  I think you are saying that they use the little
plastic chip carriers - essentially just an EPROM in a special socket. 
That would be called a MEMPAK.

Or are they putting just a 32 pin EPROM into a 66 pin MEMCAL (two rows
of 33, plugs into a header, brown or black base, blue cover), leaving
most of it empty?
