Oh and if anyone is wondering why the TO7 and MO5 beep annoyingly every time you press a key, I think it's because the first TO7 model had a horrible rubber membrane keyboard.
The MO5 was still horrible but a bit less so I guess 😅.
Subsequent versions/models had proper keyboard.
The thing they didn't have is a backspace key. Sooo annoying to have to do it in two steps (left arrow, delete).
Backspace, what a concept!
Kids, don't take it for granted!
