Has anyone worked with SD or MMC cards?  SD and MMC cards don't tolerate +5 volts.  Is there a DIP package IC that does 5-to-3 volts interfacing?  I want to be able to debug this but the SX Tech board has 5V of course.  The alternative is to breadboard it and move the SX to the board after every programming and also set up debug output blah blah.  What to do...?
