I am lost at "heads 8950". Whats that? > Also I figured a 5 volt 700 ma regulated supply wouldn't have popped > the diode should this have current limit resistors in line? The 7i42TA's are that. Limiting the current to a value below the failure of the gates in the fpga on the 7i90HD. IF you are feeding them 5 volts. What diode are you referring to? > ---------------------------------------------------------------------- >-------- Check out the vibrant tech community on one of the world's > most engaging tech sites, Slashdot.org! http://sdm.link/slashdot > _______________________________________________ > Emc-users mailing list > [email protected] > https://lists.sourceforge.net/lists/listinfo/emc-users -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
