I got my first Amiga 500 in 1987 after having played with a A1000 in filmschool. A friend of mine actually won two in some lotery and sold me one at half price. I also had an external diskdrive which made life a lot easier, lot's of disk swapping in those days. I remember buying an external harddisk for it, (20 MB storing space ! ) but that was probably quite a bit later, The program I used first and most on that machine was Dpaint and a program that later became TAD/ADPro (forgot the name). I also used Aegis animator and Deluxe Video for a while but didn't really like them. There was also a 3D program, I think it was called Videoscape.
Later I replaced that with Sculpt4D.
