New method of attaching a BS1 board to a development location

Hello!
Those of you who routinely read and comment on my musings, know about Tinkersphere, who is a small to medium sized store in the SOHO area of Manhattan. It turns out that they sell a style of jumper who can be used to connect to the pins shown on the original BS1 Carrier board.

This is "Male to Female Jumper Wires (10 pack)"

And ideally it will do the same as my original idea.

    And our sponsor also sells similar cables :

    Also true.
    But I found them first at Tinkersphere. However I am indeed using a batch of the three-wire ones for the LCD displays that live here.

    Hello!
    Well I must be doing something (else) right regarding the whole business. After the usual fun and games concerning the all important method of powering the BS1 Stamp, in this case double checking that I had the wires from the battery box containing a 9V battery, properly wired. A shout out goes to Mike Green, with double the marks, for confirming that the red and black leads from the clip need to be reversed when being connected in this style.

    Anyway I connected my switch enabled connector harness originally wired for a version of the home work board, to another snap connector. The connector was part of this thing there, ordered it for the pesky board next door, but it works here:
    Arduino Battery Adapter 9V

    It was plugged into this thing:
    Female DC Jack Adapter with Screw Terminals: 5.5x2.1mm

    Attached to the screw terminals was a black adaptaplug from RS, which is plugged into an extension cable, the same firm sold for a while. The polarity on it is reversed accordingly.

    At the other end wearing a white adaptaplug also from RS is a 9V battery box from Tinkersphere (Because RS never had it in stock locally. And even Adafruit wanted a strange amount of money for it, a firm in Texas wanted a strange amount as well.)
    Enclosed 9V Battery Holder with On/Off Switch

    Currently it is running the code from the LCD displays.

  • Next the methods of attaching the display to the board.
    IMG_0004.jpg

    It shows the board now wearing a small breadboard and the wiring needed to make it work. Following this will be the attachment of the harness for the calculator.
  • Update:
    Calculator harness works. But sending the output to the display does, but not the way I wanted. However inserting the directive to insert a CR after the variable causes an odd tokenization error.

    That's the original Stamp1 translation from the Stamp2 code that was presented to us not too long ago. The Stamp2 code works of course sending to the display. I've simply stuck in the stuff needed, or so I thought.

    What I wanted was to have the thing present the debug data on one line, take a carriage return, and then do it again. That's the second line there, with the serial out to 0 command coding. It's commented out because of that error.
