Clear Cased HP-41CX

[Jurgen Keller]

I just stumbled across this article about a clear cased HP-41CX. I know of other clear cased HP calculators (Keith Midson has a nice collection of them) but never saw such an HP-41 prototype. Interestingly, a clear cased infrared module is plugged in, however, it looks to be empty.

On the same web site you'll also find a clear cased 82240A thermal printer, really nice. Last but not least there is also an article about an HP 9100 prototype, however, I already posted that link some time ago, see here.
