Hi. I'm a philosophy professor in Houston, and I use my A3000 in my professional work. I found a program called Student Aid II by Rick Rojas. I have looked at the demo that is available and like it; so I would like to use it and am needing the key. It is from 1993. If Mr. Rojas is on this forum, or if anyone can help with the registration key I would much appreciate it. I was able to get help here a couple of years ago with another helpful program for my Logic students.
