Hewlett Packard HP 28C Advanced Scientific Calculator (Made in USA)

HP-28C/S
With the HP-28C, Hewlett-Packard completely revamped the scientific calculator. This model did symbolic math, used named variables, understood many data types and was the first full
RPL
calculator. (The HP-18C used
System RPL
internally but didn't make RPL available to the calculator user.) It was extremely powerful with a wealth of functions and many features inherited from the HP-18C including infrared printing which freed the user from cable clutter, labeled soft keys, menus and the dedicated alphanumeric keyboard which made creating complex programs and expressions more convenient.
Solver
The HP-28C included a solver that was similar to the algebraic solver in the
HP-18C
, though the HP-28C could solve both algebraic and RPL expressions (programs). The HP-28C also used a different UI. Rather than using the same key to set or solve for a variable depending on whether a number had just been entered, the HP-28C user pressed the key alone to set any variable and pressed SHIFT followed by the same key in order to solve for it. Like the
HP-18C
, the HP-28C combined the ease of use of TVM solvers with the power of general solvers.
