What is the market size for a basic/scientific calculator with pure RPN mode of operation? Did HP or anyone else conduct a survey on it? My reference for a basic/scientific calculator is one similar to the HP9s or TI30XA. Probably one without programming capability. But with limited number of memory registers.
Did HP do a survey back in the 80's and decided that the market is just not there and started incorporating algebraic mode of operations into all their calculators (with the exception of the 12C, but I can see that the 12C will very soon be replaced by the 12CP)? or the market is too small for HP's appetite.
