Request for HP82143A (Helios) paper print

[Christoph Giesselink]

Meindert and I are working on a HP82143A printer simulation.

Somewhere last year I created the HP82143A printer font with the 5x7 pixel matrix for each character. As source I used the character page from the 82143A manual. But the book scans are quite worse or maybe the original manual isn't even better. So it would be best making a test print on a real HP82143A printer and taking a "high-res" photo of the paper print. I gone the same way with my HP82240B Printer simulation some years ago. Making a test print on a real printer and took a photo of the output. The photo was good enough to detect each pixel with it's position in the pixel matrix of each character.

The HP82143 has no test print showing all characters, so I wrote a small HP41 program printing the characters from 0-127 with 16 characters per line. This 16x8
character matrix helps to create virtual horizontal and vertical lines to locate each pixel corresponding to his neightbours.

The program (UTF8 text output):

Code:


          PRP "CHRSET"
        01◆LBL "CHRSET"
            02 0.12716
            03 STO 00
            04◆LBL 01
            05 RCL 00
            06 INT
            07 15.01
            08 RCL Y
            09 +
            10 1000
            11 /
            12 +
            13 STO 01
            14◆LBL 02
            15 RCL 01
            16 INT
            17 ACCHR
            18 ISG 01
            19 GTO 02
            20 ADV
            21 ISG 00
            22 GTO 01
            23 END

Does somebody own such a printer with a HP41 calculator and has the time and willing to make a test print with this program? It's important that the pixel of each character are visible to compare them with the printout.

Aattched a printout of the code above made with a beta version,

When somebody done it, it's best to put a short message in this thread that it's already dome and send me a PM over the forum if you don't have my eMail address.

TIA for your help,

Christoph
