definitive list of cases for each model calculator

[Kostas Kritsilas]

Some cases mix and match. I have a black leather case, which I believe was originally for either the HP-35 or HP-80, but fits not only the HP-65, but also the HP-41CX (as long as the card reader is not attached). I suspect that the leatherette Classic case will also fit the HP-41CX without the attached card reader, as well. I think, but cannot confirm, that there are a few other combinations that will work just fine, solely on the basis of how close the exterior dimensions of the calculators are.

Just going from the description, the dark brown case sounds like a Spice case, and the 33 is probably referring to the HP-33E or HP-33C.
