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.
