Good to know. If they are ever in stock, maybe I'll use them. ;-) > The killer feature of the 3AN parts, of course, is the internal > configuration EEPROM. 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. -- Ben Jackson AD7GD <[EMAIL PROTECTED]> http://www.ben.com/ _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
