> Hallo Nils, I'm the intended recipient, so I guess I'm allowed to answer but not to quote... There are different ways, but selfmade solutions usually use the SPI-bus to communicate with the SD-card. That's a 3-wire-serial bus with a clock line driven by the bus master, and MOSI (master out slave in) + MISO (master in slave out) data lines. SD-cards operate at 3.6V max so you'll need a voltage conversion 3.3V <--> 5V if you want to connect it to a 6522. You could do that serial stuff in 6502 assembler (I know sb who made a SD-card interface for a LPT-port and uses it with Z80 assembler in software), but it gets very slow. sd2iec is free software, GPL licenced.
