    Re: Bob Goethe's Mark 2 Navigators slide rule, test drive comparisons.

    Hello Bob and Sean,

    For a bit of fun, I've used your posted nav-slide-rule-1a  image to make a 'digital slide rule simulator'!  It is easy to use and, with screen zooming, very easy to read. There must be a small accuracy loss due to original image and screen granularity. 

    The attached screenshot shows the slider and cursor in different positions. The lower image also shows Sean's illustrations visible behind the slider. The software is a .html file. I am not posting it here as it uses your intellectual property. However, if you reply to my gmail.com address which is 1billritchie I'll gladly send it to you. Alternatively, I could post it here if you both so request.

    Regards
    Bill Ritchie.
