I first got hooked on programing with the TI994A. After it finally lost all support I reluctantly moved to the Apple IIe. Thank You BeagleBros for getting me through. I wrote programs for my Scuba buisness during this time. Currently I am a Database manager and software developer. I started with VBA and VB6 and now having fun with VB.NET
