Hello, Now that there seems to be a trend toward more reasonably priced 68000-based personal micros (e.g. the new ataris, mac, etc), it might be a good time to get some feedback from knowledgable people about some of the available Unix-lookalike OS's available. Recent ads in UNIX World and UNIX Review, among other mags, have mentioned OS/9 68000 and TSC's Uniflex. Would anyone be willing to comment on these systems, with regard to such topics as: 1) portability to new machines (personal experience with the above OS's would be good to share), ease of writing device drivers, company support for ports 2) performance on "minimal" hardware (meaning no memory management, 256K or so bytes of memory, floppy-based file systems...) 3) any other pertinent comments - software tools available with the standard package, quality of C (and other langs) compilers available, application support - you get the idea I have experience with porting Whitesmith's Idris to the Sage IV and Sage II, so I am not new to this. Mail to me or this newsgroup, my address is (I think, I am new to USENET) seismo!rutopaz!biggers

I, too, would like to know about Unix(tm) ports to a 68000 based machine. I'm considering one of the Sage computers but I would like to know what versions of Unices (is the the proper plural form?) are available. However, I would prefer a 'real' Unix, 4.2BSD preferably. I've found that these 'lookalikes' tend to leave out some of the more nicer features of the operating system. robert -- Robert Viduya Office of Computing Services Georgia Institute of Technology, Atlanta GA 30332 Phone: (404) 894-4669 ...!{akgua,allegra,amd,hplabs,ihnp4,masscomp,ut-ngp}!gatech!gitpyr!robert ...!{rlgvax,sb1,uf-cgrl,unmvax,ut-sally}!gatech!gitpyr!robert

Without memory management things are bad on a M68000. You get to swap for every process switch, unless all the processes are linked into the proper places at load time by some kludge. The Chromatics, a very early UNIX system, ran IDRIS, a very early M68000 UNIX port, in this way. Miserable. Sadly, an 8088 with no MMU is in some ways easier to deal with than a M68000 with no MMU.
