this was left behind by my son. Don't know anything about this stuff except I remember he was changing it out to enlarge for memory needed for a new game. For any info. look close at the pics. I don't know what size it is.. if you are looking then you know what you are looking at. Emptying the nest and it all has to go. just picking it out of the moving boxes as I come to it and putting up ads.. I will be a year with all these ads. be sure and look at the other stuff and keep coming back.. Thanks for looking and I do ship FAST!
