An excellent and useful chart Martin, thank you for sharing it!

The various devices mentioned do not include the original HP-49 - does this machine act like a 48G or the later machines? I have one, but honestly use only very rarely; I much prefer a 48G or 50g. I was away from the hobby when the 49 was released, so never learned it's details very well.
