Alps GlidePoint Keypad for Macintosh

These are photos that I received from ricercar at Geekhack in 2014; I was hoping to obtain either better photographs, or the keypad itself, and neither option ever materialised. This keypad is significant in that it is the only known example of Alps SKFRAD. It is also interesting in being an Alps-branded product manufactured by Datacomp; if anyone, I would have expected this to have come from Forward Electronics!
