Thanks to Koopa (cheers mate

) I now have a working internal drive for my 1200 tower. For info, with some external drives you can just take the drive mechanism out of the case and plug it straight into the Amigas internal bay. They're not all like this however. Some have a different connector and you can't tell until you take it apart. I know this because I also bought an external drive on eBay (it was dirt cheap so I thought, 'why not?') to try out. The connector on the back of the drive mechanism of this one was much smaller than the standard drive. Anyway, I'm now in the position of having a working and usable tower system, although the case itself is very tatty.
Now I have a couple of other questions:
1. In the process of my attempts to get the drive installed and working I damaged my beloved mint copy of Alien Breed - Tower Assault (aaaaarrrrrrghhhh, much wailing and gnashing of teeth, and a not inconsiderable amount of swearing). The Alien Breed 2D series of games is one of my favourite Amiga games. As I have the original I believe I'm entitled to have a back-up copy for my own personal use for just such an occasion as this. Unfortunately, I don't have a back-up copy. So is there a kind soul out there who'd be willing to copy theirs and send me it for a small consideration?
2. The Amiga tower system came equipped with a Zorro expansion board. This is something I'm not familiar with and have been unsuccessful in my attempts to find information regarding it on the net. I can find plenty of sites that mention it, and pictures, but what I really need is an instruction manual that tells me what all the slots on it are for and what I can do with it. Does anyone here have any info?
