I know they put out 6.05, 6.08, 7.0, 7.0.1 and 7.5.3 at one time (if you try clicking on the links now it says error). As I stated I have a macintosh SE and do not have a FDHD. I need system 7.1 and not the other systems becuase 7.5.3 is too slow to run well on it and system 6.x is too old to run the software I want. Also I curretnly use system 7.0.1 but need to upgrade it for an accelerator card I have that requires either 6.x or 7.1 and will not work right on 7.0.1 or 7.5.3. I have an Iomega ZIP drive to put the disk files on and I have some blank 800k floppy disks but I would like to get system 7.1 somhow legally through apple. I don't understand why they would release older versions and newerverions of system software without the one people need đ. It's not like I'm making money off of this I just want it to get my old mac SE working correctly. Back when it was purchased its inital price was $3,900 and the extra hard drive cost a lot I think apple could at least let me have a copy of the OS that I need for it...
