tamper0616 / x11-calc-hp29c Goto Github PK

Simulators for the HP 35, HP 80, HP 45, HP 70, HP 21, HP 22, HP 25C, HP 27, HP 29C, HP 31E, HP 32E, HP 33C, HP 34C, HP 37E, HP 38C, HP 67, HP 10C, HP 11C, HP 12C, HP 15C, and HP 16C written in C using only X11.

Use of any language extensions or non standard language features has been avoided in order to try to make the code as portable as possible.

Should compile without modification on Linux, VAX/VMS, and Tru64 Unix.

Unlike all the other simulators the ROM images for the HP10C, HP11C, HP12C, HP15C, HP16C are not defined in the the source code and must be loaded from a separate ROM file.

06/03 - HP10C, HP11C, HP12C, HP15C and HP16C are now working!!

20/01 - Now compiles cleanly on VAX/VMS.

10/01 - Split code into two branches, stable and unstable.

04/01 - Added HP35 (50 years after the launch of the original)!

• Fails self test.

• Cannot read or write to magnetic cards.
• Has continuous memory.

To build the simulator on Linux check that you have all the prerequisites installed then download the source code from github and unzip it (a new folder will be created to automatically). Then change directory to the new folder run 'make all' build all the simulators.

e.g:

$ wget https://github.com/mike632t/x11-calc/archive/refs/heads/stable.zip
$ unzip stable.zip
$ cd x11-calc-stable
$ make all

$ ./bin/x11-calc-29
x11-calc-29: Version 0.4 [Commit ID: 81c55be] 16 Oct 21 21:15:00 (Build: 0067)
ROM Size : 4096 words

The following keyboard shortcuts should work on Linux:

'0' - '9', '+'. '-'. '*'. '/' and 'Enter' should do what you expect them to (when using numeric key pad you need to use numlock as usual).

'f' and where applicable 'g' and 'h' correspond to the shift keys.

'Esc' or 'Backspace' corresponds to 'Clx', 'c' to CHS, 'e' to 'EEX', and on financial models 'n' and 'i' correspond to 'n' and 'i' if not shifted.

On programmable models 'A' - 'E' correspond to the function keys where they exist and 'Space' to 'SST' if not shifted

'Ctrl-Z' Quits, and 'Ctrl-C' does a reset. For models with continuous memory 'Ctrl-Z' saves the current register contents, and 'Ctrl-C' restores them to the original saved state.

For models with continuous memory the contents of program memory and data registers are saved in a hidden file in the users' HOME directory when the program exits or the calculator is switched off, and restored from this hidden file when the simulator is loaded or reset using 'Ctrl‑C'

~/.x11-calc-nn.dat

When starting the simulator the name of the data file used to restore the saved state can be specified on the command line allowing previously saved copies of programs to be loaded automatically when the simulator starts or the simulator is reset using 'Ctrl‑C'. However, any changes will be saved in the hidden data file.

Clicking on the On/Off switch will turn the simulator on and off, but if you hold down the off switch down for two seconds the program will exit.

You can start the simulation in trace mode using '‑t', or in single step mode using '‑s', and set a breakpoint using '‑b <octal address>'.

'Ctrl‑T' also toggles trace mode when running, 'Ctrl‑S' executes the next instruction, 'Ctrl‑Q' resumes execution, and 'Ctrl‑R' displays the contents of the CPU registers.

When in trace mode a jump to the same instruction produces no output.

No ROM images are included for the HP10C, HP11C, HP12C, HP15C, and HP16C.

The '-r ' command line option provides the ability to use the ROM contents held in an separate file.

For the HP10C, HP11C, HP12C, HP15C, and HP16C the ROM comprised of pairs of hexadecimal values as address:opcode.

0000:107
0001:04e
0002:270
0003:238
0004:2ee
0005:13f

Other models include the ROM as part of the program, but you can specify an alternate ROM comprising of pairs of octal values.

00000:00255
00001:01420
00002:00451
00003:01456
00004:01746
00005:00472

This allows you to use your own ROM images with any of the simulators.

On UNIX/Linux a 24 bit colour display is required.

Keyboard shortcuts only work on Linux.

On a Raspberry Pi the display is not updated properly if either FKMS or KMS graphics overlays are enabled. The following entries in '/boot/config.txt' should be commented out as shown.

#dtoverlay=vc4-fkms-v3d
#dtoverlay=vc4-kms-v3d

HP 67 is unable to read or write to magnetic cards.

HP 37E fails self test.

Colour palette assumes a black and white display (if your system has 24-bit colour you can modify the definition of COLOUR_DEPTH in x11-calc.h to build the simulators with support for colour display).

Not all text is visible due to the limited colour palette and the DEC fonts are missing some characters (for example the Pi symbol).
