Supported functions

All functions of the original HP11C (c)Hewlett-Packard, 1981-1989

Exceptions

  • Some functions like the Gamma function are implemented differently from the original HP11C. Their accuracy may vary slightly.
  • There are a few additions to the original calculator. 
  • The STO+Reg function is extended with STO+ ,1 to STO + ,9 as well (also for -,*,/ )
  • The unary operators are also supported on the "I" memory (STO + I )
  • Memory is not converted to program memory after 63 steps.
  • Available program memory = 999 steps.
  • Small differences in operation exist with the SST and BST keys, they are not repetitive.
  • The GTO .nnn combination is not supported, use a click on the program listing in the Program Memory window instead.
  • Keep in mind that programs made with these extensions will not run on your original HP Calculator!
