Abstract : The purpose of this invention is to convert hexidecimal computer words into binary form quickly. This invention consists of a holder having a front plate and a rear plate spaced apart by spacers. The plurality of slides having conversion charts printed thereon are fitted in the space between the front and rear plates and are kept separated by guides. The front plate of the holder has two viewing slots and a slide slot. Through the viewing slot the numbers printed on the slide are viewed two at a time. The top viewing slot shows a number which is to be converted, and the bottom viewing slot shows the binary equivalent of said number. In order that different numbers may be selected by the slides to be viewed through the viewing slots, push pins are positioned through the slides and out the front of the holder through the slide slot.
