How's this for an early HP 41c?


This is one of Richard Nelson's HP 41c units. I'm wondering if this might have been his beta unit he had long before the HP 41 was announced.


Now that is old!

Does it still work?


Is that "classic" green plastic ?


I think it is the normal HP 41 plastic color. Think it works too.

Are we still doing the spoof eBay ads?
