Coconut was the HP internal codename for the original 41C, the 41CX was Honeynut and the 41CV Silverbird. There was a version known as Option 001 which was meant to be customised by the user and therefore had no labels on the upper rows of keys or on the surrounding keypad. This was the blanknut.
During the 41's life it was modified with a reduced number of electronic components and these versions became known as the halfnuts with the earlier versions becoming known as fullnuts. As already mentioned in an earlier post the display is the obvious external difference bewteen half- and fullnuts. I think all three types, 41C, CV and CX can come in either half- or fullnut versions. I am not certain if HP used the halfnut or fullnut designations internally or whether these originated from enthusiasts - anyone know?

PS - I think that one functional difference is that with halfnuts it is possible to program the display to get a full set of lower case characters and also to adjust the contrast of the display.
