Hewlett Packard 9825A 9872A Message #1 Posted by Norman Sherfield on 15 Jan 2001, 1:57 p.m. I have a framed image (using red, blue and black ink) looks like it was generated mathematically with a computer. Its says BIRTHDAY DEMO on the top left corner and HEWLETT-PACKARD SYSTEM 9825A/9872A on the top right corner. Framed size is 11 inches by 14 inches<P> I do not know if this is a demo for someone's birthday or a demo for the birthday of the System 9825A/9872A. There is no date to be found anywhere on the framed image or back of the frame. Anyone have any ideas? I can send a jpg of the image if interested? Norman

Re: Hewlett Packard 9825A 9872A Message #2 Posted by Don Williams on 16 Jan 2001, 8:58 a.m., in response to message #1 by Norman Sherfield The "Birthday Demo" was a program supplied on tape with the 9825 computer/9872 plotter system. The program prompted for your birthdate and using this input as a seed, plotted a diagram of vectors unique to your birthdate. I remember that it was fascinating to watch the plotter " do its thing " , and produced an image for everyone in my family based on their birthdate.
