I actually bought a A1000 in 1990, came with some software. (In fact, I traded it for a TurboGrafx-16). In 1991 I landed a good job, and purchased a used A500. Added the ram expansion, "fatter agnus" and eventually graduated to KS1.3. I'm trying to remember the fist thing I did with it, but considering that I had the A1000 before.... I think it was mostly to play some of the titles I had in PAL.

After a little bit an oppertunity presented itself and I traded the A500 for a LtKernal 40Meg HD for my C=64 for use with my C=64 based BBS.
I bought another A500 a few months aftwards. I also upgraded the processor to a 68010, added a ZorroII side car that had a GVP harddrive +HD and 8 megs of fast ram. I also had a Vidi Amiga 12. By then I was playing around with Image FX, CineMorph and the Vidi Amiga 12 making little animations.

That A500 got traded in towards an A1200 eventually. (But I still have an A1000 in my closet.

) [Oh, that A1200 was traded away for a GVP Impact Vision 24...]
