Solved!

Entering program-steps on an HP 30b emulator

HP Recommended
NW238AA
Microsoft Windows 7 (64-bit)

I am an HP-fan since the HP-25 and though I own an HP-48GX too, weeks ago I bought an HP 30b, only to "repurpose" it into an WP-34S.
But before doing this, I wanted to learn about all the features of the new "business professionell", e.g., the difference between an old RPN-stack and the RPL-stack (with an extra input-register of the 30b) and: I want to write short, a little sophisticated programs.

To use those programs further, I was glad to find the download-URL of the HP-30b-Emulator (© 2009 Version 2012 12 10 Rev: 19045).
Although there ist an "Emulator Help" available, I can't find, how to manage a [shift+hold] [...] via the PC-keyboard to enter the programming-commands of the 4 upper key-rows, e.g. Lbl, Call, Stop, R/S, RTN and the marvelous SOLVE.

 

Thank you for helping me to manage that problem!

On the PC keyboard just press SHIFT key and keep it pressed and at the same time press Lbl, Call .... on the emuator. If the left shift key does not work check with the right shift. If this will not work give the link to this emulator

Hi,

 

Have you clicking the on-screen calculator shift using the right mouse button, (this simulates a shift-hold in the 50g emulator, maybe it will too in the 30b emulator).

Hi!

Thank you for your aid. Although, nor the left - nor the right shift key did work, but your answer encouraged me to try more key-combinations.


Succesfull was:
1. Enter the regarding 30b-program

 

2. Press and HOLD the caps-lock key! Do not note the colour oft the shift key. Important is, that the caps-lock-LED on your keyboard is light.

 

3. DOUBLE CLICK with the left mouse key on one of the 19 programming commands. This will do for commands without a parameter, like RTN, R/S, ?> .
3a.Commands with additional address like Lbl__  or DSE__  or Disp_: Release the caps-lock-key so that the caps-lock-LED is off.
3b. Type in the address with the numPad, (right side) of your PC-keyboard.
Don't look at the orange / blue color of the 30b-shift-key. Sometimes, this doesn't correspond with the ON/OFF-status of the caps-lock LED.

 

Now Happy? Not quite, there remains one problem:
When I have left my program, I will see on the display e.g.

Prgm 2
10.042

but then ***I can't evoke the SOLVER***, for solving Prgm 2 for one of the 10 memory registers.

 

Can you get some advice from an HP-software-engineer?

Thank you very much for your further help!


Regards!

Hi,

 

Thank you for coming back on this.

 

I found the following on hpmuseum.org forum:

"right click, then left click with both buttons"

 

see message #20 by Tim Wessman in this thread:

http://www.hpmuseum.org/cgi-sys/cgiwrap/hpmuseum/archv021.cgi?read=238796#238796

 

The method above takes some practice:

     on the button of the function you want, right mouse click the press and hold both mouse buttons for at least 1 second

 

I installed the 30b emulator on an XP computer and found:

- the emulator help is for the 20b only, which does not have any shift-hold functions, so that is not described

- having the calculator's shift key mapped to the keyboard caps-lock key is stupid

 

I commend you for your perseverance 🙂

 

Regards.

-Bart

Using SOLVE with the HP-30b emulator

 

Having left your program with [ON/CE], the display shows row 1: Prgm # and in row 2: bytes.checksum

 

- Press [ON/CE] again

 

- Press and HOLD the [CAPS-LOCK] key!

 

- DOUBLE CLICK on [÷ / Math] and ***HOLD the left mouse-key  DOWN***, - DON'T RELEASE the button!

 

- Display shows SOLVE as long, as the left mouse-key is pushed down

 

- ENTER via numPad the number of that register you want to solve for

 

- Display now shows in row 1: last program step executed

                                          in row 2: RESULT

 

 

Your hints gave me food for new thoughts!

Thanks and kind regards!

ohne more Question:

I can't translate (into German) your remark "caps-lock key is stupid"

Can you, please, express that sentence  in more other (english) words?

 

Thanks and kind regards!

Hi,

 

To solve e.g. Program 2

 

When the display shows row 1: Prgm 2 and in row 2: bytes.checksum

 

With pointer on the SOLVE button, press and hold right mouse button, then also press left mouse button

(you should now be pressing both mouse buttons)

Display row 1 will show "Solve 2 ="

Let go both mouse buttons

 

Now select variable that you want to solve for either on the emulator or keyboard.

 

Display will show result

 

Use the above mouse button procedure for all programming commands (and all shift-hold commands).

 

Kind regards.

I think it was stupid of the emulator programmers to use the caps-lock button for the keyboard equivalent of shift.

 

Usually the keyboard shift button is used, and for emulators with multiple shift the Ctrl or Alt button is used for the second shift function (e.g. on the 35s emulator the keyboard shift is calculator orange shift and Ctrl is calculator blue shift).

 

Kind regards.
