DISCLAIMER : The circuits described in this section are the authors best approximation of what might be successfully be implemented. For the most part, they have not been actually been prototyped and made to run. Only circuit 5 has actualy been impemented. They are a composite of designs done over the years which have been successful. They should be able to be built, but you may discover some small errors in the schematics, or PAL equations, that will need to be corrected before they will run properly.
NOTE : Due to a bug in AmiPro which almost cost me this entire document, the schematics for the application circuits will be included with this paper as separate postscript files. OK. Enough theory. Let's get down to some actual circuits. In this section I will present some actual design attempts. We will start off with a simple design, easy to implement, then move on to more complex things.
