HEY, I had an 85 for 2 years now, and just got an86, but I've always wanted to know, what is the difference between TI-BASIC and loading the TEXT files manually into the calculator? I was also wondering, where can I learn assembly for the 86 and how much more efficient is programming in assemble versus typing programs into the calculator manually?
