I’ve read the glut-specification and there is a dial & button box explained as “A sophisticated input device consisting of a pad of buttons and an array of rotating dials, often used by computer-aided design programs.”
But I still haven’t got a clue what it looks like (especially the word ‘dial’ cofusses me a bit). I’ve searched google for a photograph of such a device but haven’t found one.
Could someone explain me what this is? And is it wide-spread? (what about spaceballs? has anybody got one?)
Thanks in advance.
