Great, thank you. Unfortunately I cannot get any of the images to work. I think it is due to the fact that I have to decompress the zip files and the Lisa doesn't like that. If I try and decompress the zip files on a power Mac then the disk image will mount using disk copy 4.2 but if I decompress them on the original Mac mini they are not 'seen' by disk copy? Does anyone have any ways to get round this? The obvious one is to get a unzip tool on my power Mac, but everytime I use my tool that I already have on there I get an error code thrown at me (error 39, I think.)

Edit: also is there a way I can compress the files to have the extensions .sit files? That's how I got all of the Lisa pascal disk images to work as they had that extension and so could be expanded on a power Mac using StuffIt. My older generation Mac's can't handle zip folders.
