MacTracker claims 7.5.5, I can't dispute that as I haven't tried it but I expect it might not do much good (no RAM left for applications). Same is claimed for the Mac SE and Classic and PowerBook 100. MacTracker doesn't report the Outbounds (Jeff?) but since (I think) they used motherboards from the above systems, I would be surprised if they ran later versions. I'm not aware of any later 68000 Macs (or indeed, any others excepting the 128k/512k/fat Mac series, none of which went to OS 7.x). If the question was whether 680x0 processors support OS 8, the answer to that should be yes. Quadra 950 is claimed to run MacOS 8.1, as is PowerBook 540/c and others, again per MacTracker (which is a reasonably useful resource for these machines). The Mac OS category in the same program says the same thing, giving requirements as follows: 7.1 68000 or later, 2 MB RAM, 4 MB hard drive 7.5 68000 or later, 4 MB RAM, 21 MB hard drive 7.6 32-bit clean 68030 or later, 8 MB RAM, 40-120 MB hard drive 8.0/1 68040 or later, 12 MB RAM, 195 MB hard drive 8.5 PPC, 16 MB RAM, 150-250 MB hard drive 8.6 PPC, 24 MB RAM, 190-250 MB hard drive Wow. Looking back, it's amazing how fast requirements shot up. I'm really glad I sort of sat out that period as far as buying computers. Our main home system was a Mac Plus until we leapfrogged to a Powerbook 3400 (which is still our current system). Nice to go computer-buying budget. FWIW, hit http://www.mactracker.ca/ if you want to grab the (freeware) program I'm looking at. Gotta love these guys, there's a version which runs on MacOS 8.5 still available, as well as one for (spit) Windows and (grin) *iPod*.
