Like many here, I have several Amiga systems as well. You can find all their specs on my site.
http://www.geocities.com/irperez/It just lists all of my machines, maybe I will update the site with some specific uses of each machine. I can summerize them as follows: A4000 (basic usage), A1200 (Games/webserver), CD32 (games), CDTV (CDPlayer), A500/A2000 (Museum pieces).
