The Apple ][+ (which I bought in 1981) had left and right arrow keys, but no up/down arrow keys.

It’s been so long since I used a ][+, I forgot that there was a right arrow key. I thought there was only a backspace ley, but there was, along with a “rept” key which I’d completely forgotten (not to mention that horribly-placed reset key).
