RPN-38 CX is a photo-realistic simulation of Hewlett-Packard's third-generation programmable financial calculator HP-38C.
Released in 1978/79, the HP-38C and HP-38E were the high-end business members of the so-called "Spice" series. The HP-38E was introduced first, followed a year later
by the HP-38C which added continuous memory. They were discontinued in 1981 and 1983, respectively.

Also shows extra functions NOM and EFF.
- Show Key Fronts: if enabled, tapping the g prefix key will show the hard to read functions printed on the fronts of the keys on top of the keys.
