My first A500 (and my very first Amiga computer ever) was purchased quite a while after I saw one at a Software Etc. store in a mall in Eau Claire, Wisconsin. Had to save up money for a long time. Gee, that was a long time ago! It was running the "El Gato" demo. Bought with 1 MB of RAM and an additional floppy drive. It has changed a lot since then. You can see what I've done to that very machine (yep, I still have it to this day) at this
