Mine too! That was when I first decided I might want to be a writer, so I asked my parents for the word processor cartridge “AtariWriter.” I wrote a 60-page novella on it back in 1985. By the end, saving the document on the tape drive took ages.
That was the only software I had for it, other than the primitive games I programmed for myself in AtariBASIC. And that was the last computer I owned until 1996 or so.
