| Abstract |
If you have a computer with high-resolution graphics, then you already own 99% of a digitizer with equal resolution. This article tells you how to use a sheet of half-reflecting plastic to build the rest. The modular demonstration program should be easy to customize to your application. The article also describes a 'crashproof' disk access which should be of interest to those who have puzzled over details of the Applesoft ONERR GOTO command. |
