My first Amiga was the A500. The first programs I run were some public domain disks that I was given from the store where I bought it. They were 17bit disks (slideshows I think) and some demos. I didn't mess with workbench until I bought some blank disks, a few days later, to make copies of it and keep the originals in a safe place. They are still in that safe place. I really liked WB1.3.
The A500 was also a goodlooking machine. I used to spend time just looking at it when it was off. Well I still do some times ;-)
