Hi Elizabeth, I am sure SD cards of 2mb capacity are still available down here. They still work in any!! KN7 as far as I know.
I will enquire, and if I am correct I will let you know and you may be able to buy them on the net. Otherwise I suppose I will have to snail mail them to you. Surely you would still like to stay in the 21st century. and avoid using floppies. Although I confess to having quite a collection myself. (They are becoming scarce here as well)!!
