HP-67C Simulator

[teenix]

Hi all,

The 67CX I posted unfortunately has multiple bugs and is going to take some time to fix. It turned out too complex to transform into PIC code with all those associated future bugs as well.

As such, I decided to replace it with another simulator for the HP-67 which is simpler but maybe more flexible and if I get time, will be easier to transform into PIC code.

The calculator operates as a standard HP-67 with the extras as listed below.

This one supports program modules that are containers for up to 12 HP-67 programs. These can be loaded into the calculator and the 12 white buttons 0 - 9, decimal point and R/S execute the function via the [h] [f] function keys and can also be called from within a running program.

For example, button [1] can have a module program that calculates the ceiling of a number. Keying in 5.1239 and pressing [h] [f] [1] will run the program and display 6.00.

Keyboard overlays can be designed so that when a module is loaded the matching overlay will be displayed on the calculator face.

. . . .

All operating code (except memory access) is still based on original HP code
999 program steps
100 memory locations
5 level subroutine stack
Keyboard map or (7 segment) alpha program display
Code editor
Module Editor
Up to 12 HP-67 module programs can be executed
Different modules can be loaded
Animated card reader with Park function
RAM memory viewer
Constant Memory

These simulators gave me something to do while away, but hopefully I will be going home soon now that Covid cases here are so low that the state border restrictions are finally lifting. Unfortunately that means I won't have as much time to fiddle with simulators.
