After all these years, I have a chance to obtain an excellent condition KN-7000 once again.

But it's been a very long time since I've last owned the 7000, so long ago, that for me, floppy disks were the norm for external file loading and saving.

I remember most of how the OS works, but since floppies are long obsolete, I would assume the SD Card is now used to completely replace floppies for style, song, registration, etc. loading and saving. Correct?

And on that note, is there an SD Card size limit for the 7000, and any brand recommendations?

Thanks
