Here are the infos about the psx memcards.. anyone wants to build an interface for the PIC? #http://www.ticalc.org/pub/text/hardware/ti2psxmem.gif# There's also a textfile available, which describes the protocol. It's called ps-e.txt . gzipped is about 4k.. Ask me privately and i'll send it to you. Unluckly i cannot remember where i've got it from... :-( -- - *Alex* - http://freepage.logicom.it/azummo/
