Now that I know what I'm doing,the tape plays, but I've yet to successfully load anything. I've tried to load my States and Capitals cassette, since it's the only original cassette I have. I put the tape in, make sure it's rewound, type CLOAD, press play, then enter. The tape starts loading, but it never loads. Mostly because the rubber band keeps falling off, it's really irritating. It might be to small. Anyway, when the rubber band doesn't fall off, I've gotten errors like 138 and 140, but mostly 140. I haven't tried saving a program, just loading. When the tape is loading, I do here the "digital, computer type noise" the instruction sheet describes.
