A challenge that could be mastered.

Actually there were 2 different HP-10B II models with quite different case designs (not sure if f/w is different).

Also, you forgot the current HP-10BII+, an excellent and feature-rich financial calculator (except possibly the HP-27S, a strong candidate for best HP Algebraic machine ever, IMHO).
