What is the MINIMUM Hardware?? I'm pretty sure that there exists a port of Unix (whether BSD or not I'm not sure) for all PC-DOS machines. Not that it's any good; your speed would be atrocious if you even attempted to use daemon-ing, etc., to get multitasked efficiency out of your BBS (a la by backgrounding message saves, etc., etc.). '286 ports are more common, and quite a bit faster; I think someone has (finally) produced a protected-mode-based '286 Unix; am I correct, all you netters? Several sources have come out with '386-based Unixes, all of which are bound to be rawther nice. I would strongly suspect, though, that the best Unix bang for the buck is in the AT&T Unix PCs, which are apparently proliferating as of the past few years. Those things have superb internal architecture (Hey, Unix PCers, what's your CPU? I know your RAM is super-fast, among other things), and seem to be the only really consistent lowest-common-denominator Unix machine. Do I hear any rebuttal? ||Jonathan E. Brickman

Hope it helps ||- \_o ||- / WARNING: UNIX-PC is no-longer manufactured, AT&T no longer supports the software unless something is _REALLY_ broken. And even then they are slow to answer. ON-THE-OTHER-HAND: GNU stuff has been ported to this machine and lost of other free is available via THE STORE and an extremely dedicated core of users.
