Hi, i just picked up a couple of jornada 420's off of ebay my self....i have a 64 meg card in there right now...I'm still learning my way around this pspc myself...Im use to hpc's though this is close in operating system, to hpc pro 2.11, its not a cigar
.....anyway...you can use as big of card that can fit in there man, even a micro drive......Steve
