I've found one source (Rochester Electronics) that seems to have them, but they have a minimum order of 2778 pieces, which is a bit of overkill compared to the 150 we need to build 50 boards.  We'll use that source if the other options turn up dry.


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.
