Richard, Does anyone have a PDF copy of the Motorola 6800 chip datasheet? I downloaded a copy from somewhere yesterday and the strangest thing happens. When viewing the PDF, it shows on the screen as a positive image but when printing, it prints as a negative. On the print page make sure 'Print as image' is ticked. This should fix the -ve image. Lee. ---------------------------------------------------------------------------- ---- This email is intended only for the above named addressee(s).
