HI all I am new in this forum however using casio keyboards for along time .
About 2 years ago I bought a "GOTEK" floppy drive emulator for my WK1800 and still runs !
If you a little bit techie you can replace the old floppy drive with it and save/load your files digitally on USB stick .
However mine came not with any schematics and had to fiddle a lots to get it working .
The new drive have some problems as it's maybe normal .
1 if you load or save some thing you cannot switch to another directory ,,only solution is to switch keyboard of and on ,
All works but a little sloppy in my opinion .
If there is any one interested for this I will post more
