Yes there are external and internal card readers for the mpc2000xl. You can get the external off of http://www(.)scsi(for)samplers(.)com/cardreader.asp and buy an internal from off ebay or something. Its a ton of threads on the internal.
(remove the () and you will be good to go. Tutor's site blocks out that website so I have to set it up like dat in order for it to post up and not get decoded to another website.)
