Your First Handheld?

[DaveBr]

The first calculator I remember using was a NS 600 4 banger. I remember it used a type of rpn, but used the + key as an entry separator. I used a Rockwell calculator in Jr. High and High School and a TI-30 in college. I remember my class mates on the G.I. bill all using HP 21s. The instructor used a HP 45. I was so envious.
