Good to know.  If they are ever in stock, maybe I'll use them.  ;-)

Altera OEMs the ST M24P* series of serial flash memory.  So (if I remember
my parts right) a EPCS4 is a ST M25P40.  THe ST parts are a loooot cheaper.
I am factoring that in to the price equation -- the Altera parts are
way overpriced.

BTW, I just found out that that there's a "Serial Flash Loader" (SFL)
that lets you program a EPCSn style chip via the JTAG port, so you don't
really need the separate config header.
