Hi, This question has probably been asked before, but I don't follow this newsgroup. I'm thinking about buying an LC. I'm too poor for an IIsi, and for my purposes (word processing, some small programs) a IIsi would go to waste. My concern is, will the LC be able to run System 7.0? I know it won't have the virtual memory capabilities, since the LC doesn't have an MMU, but it seems like you should still be able to multitask without one. But if the LC can't run System 7.0, it seems to me that all the LCs sold now will become orphaned in a couple of years. Incidentally, I have heard MANY conflicting stories about this issue. Does anyone have the real story on this? Thanks in advance, Scott Kell

Yes, all Macs will be able to run System 7.0. Although, I'm not sure
about the 128K Mac and the Mac 512K, so maybe I shouldn't say all.

But if do want something to think about, I don't imagine System 8.0
will run that well on an LC. Isn't Apple planning a late 92 release?

Fer crying out loud, people, System 7 IS NOT EQUAL TO virtual memory! The answer to a memory crunch is to buy more RAM... it's cheap. System 7 addresses multitasking, publish/subscribe paradigm, significant user interface goodies, built-in file share, and lots more. ALL of that runs without a PMMU. Virtual memory is a boondoggle devised in the days of Sculley's expensive RAM blooper. It'll be nice to have it there as an occasional stretch-the-envelope thing, but if you wind up using it every day, BUY MORE RAM. +------------------------+---------------------------------------+ | Stephen Fleming | In ten years, computers will just be | | fleming@cup.portal.com | bumps in cables. --Gordon Bell | | CI$: 76354,3176 +---------------------------------------|

The minimum requirements to run System 7 are 2M of RAM and a hard disk.

System 7.0 can run on any Macintosh except the original Macintosh and the Macintosh 512; those early models do not have recent enough ROMs. All later models, including the Plus, the SE, the Classic, and the LC, can run System 7.0. However, System 7.0 does require 2 Meg of RAM and a hard disk, and of course virtual memory will not be available on machines that do not have a PMMU. ========================================================================== Rick Holzgrafe | {sun,voder,nsc,mtxinu,dual}!apple!rmh Software Engineer | AppleLink HOLZGRAFE1 rmh@apple.com Apple Computer, Inc. | "All opinions expressed are mine, and do 20525 Mariani Ave. MS: 3-PK | not necessarily represent those of my Cupertino, CA 95014 | employer, Apple Computer Inc."
