when i read.... "Amiga fan. I'm 17,"... i did check the date on the post... its still 2009 and not 1990. hehehe....
all you need for that a500 to do some seriouse tracking is a hd and more ram if possible. other than that you need a parallel cable and amigaforever+amiga explorer, this you can buy or download from shady places for free.
