Description:
Text based noughts and crosses. Works best on 9700 calcs, needs slight editing for 9800s to cope with different screen width. Better on 9700s, as it is based on a scrolling bug which was fixed for the 9800. The numbers on the keypad represent the squares. The screenshot was taken using Martin Poupe's excellent calculator emulator, freely available at http://pages.whowhere.com/computers/martin.poupe/. The .cas files needed to run noughts and crosses on this emulator are available in zipped form in noughts.zip. Run the emulator on ~noughts.cas from whichever directory you extract the files into. |
