Rochester Electronics is the "leader in the trailing edge" of 
electronics - they buy old stock and more importantly old mask sets and 
fab equipment. Their whole business is supplying past end-of-life parts 
for replacement purposes.

Their minimum order probably means they need to do a fab run on some 3" 
or 4" wafers or something.  Heck, just getting small diameter wafers is 
probably a challenge.

They are an invaluable (but expensive) service for people maintaining or 
trying to duplicate an older design.
