I absolutely adored the Amiga, my favourite system ever! I always wanted an Amiga 1000 from when I first saw them but I was never going to be able to afford it so was happy when the A500 was released. I eventually bought one and loved it from the start, so many cool games and loved its music ability with tools such as OctoMed (I think?) and tinkering with Deluxe Paint. Such happy days. I then upgraded to the 1200 and even purchased the CD drive for it as well as other upgrades, it really was such a fantasic machine. My biggest regret was selling all my Amiga kit, never shoud have done it but I always wanted to move on to the latest new shiny tech and the PC was tempting me with games like doom and Wing Commander etc.
Anyway enjoy it, and I hope it does boot up for you!
