A long time ago I installed a drive in my A1200,(it is now in my Pegasos) and installing is very simple (I can say that because i'm not very handy). Most important is that you need to install some files from your WB3.9 CD to your harddisk. Look in the DEVS/Dosdrivers for ZIP and install them on your harddrive and then you have to look for the Iomega 'IoTools' in the Tools-directory to install your Zip-drive. If there are more questions I can ask my son to help you.
Good Luck
Tom
