Most minimalistic (RPN) calculator
Hello!

Recently I acquired a "lot" of calculators, which also included a (boxed! and seemingly unused) "National Semiconductor Model 600 Personal Calculator". Made in USA in 1973 or 1974.

I think this must be the most minimalistic calculator in my collection. Six digits, integer arithmetic, no key for a decimal point. The "+" key performs the (unlabeled) Enter function as in similar units. The little "decimal" switch on top of the keyboars is really a gimmmick because it only turns on and off a fixed decimal point LED between the second and third digit from the right.

Does anybody have an even simpler (RPN) calculator?

Regards
Max
