On the old "Beagle Bag" collection for the Apple ][, there were some impressively done programs in "Magic Pack". In one of them, you are directed to hold a playing card up to the screen, type "RUN", and the computer scanned the card and told you what type it was. In another, called "Plenty Questions" (like 20 Questions), the computer asks a bunch of Yes/No questions which you answer and are typed in. And the computer could guess it right 100% of the time. All **assuming** that a sufficiently trained person was sitting at the computer keyboard. For the card scanner, you would type "3CN" (as the letters "RUN" appeared on the screen) to indicate that, say, a 3 of Clubs was being held up to the screen. For "Plenty Questions", you get to type one letter of the object in response to each Y/N question. Of course, "Magic Pack" depended on a good amount of showmanship on the part of the computer's owner as he dupes his friends into believing the mystical powers that his lowly Apple ][ has acquired. And not doing the tricks so often that the audience figures out what's going on! -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927
