This is probably more aptly called a demo model rather than a prototype.
Computer makers would sometimes create a handful of a model prior to launch
to privately show it off to the press, retailers, investors, etc. Compaq
once gave me a laptop to preview for BYTE that was in a clear case. It was
essentially a production unit on the inside.
My guess is that HP made fewer than 10 of these HP-85s in a clear case. This
is a way cool find.
