Blanknut
Message #1 Posted by Darren Tschida on 1 Sept 2004, 6:21 p.m.

I've apparently got a 41 blanknut. Can anyone tell me how it compares to other 41 models, and what the story on the "blanknut" thing is anyway?

Basicly, it's a specialized HP-41 with no labels on the buttons. It was meant to be heavily customized.

IMO it's a 41C with only a few key legends. The idea was to have overlays and a ROM module to allow special applications (insurance, tax etc.) - the advanced features were simply hidden from the user. Look at it as some kind of small, cheap, portable computer (and not pocket calculator)
