But a faster clock and extra electronics I don't thinks so. >> Does it take an eternity to boot it up, and do you have to leave it >> on all the time, or can you just shut it off every now and then like >> the DOS boxes?? > Shutting it down is just about manditory on a periodioc basis > for system V rel 3 or eirler behaviors.

I have worked with many different favors of Unix including SVR2, BSD4.[123], Suns and Pyramids. The only thing this kernel doesn't have that a normal SVR1.x would have is accounting. But is also has paging, shared library and BSD ls & more. Many of the programs ex: more, compress, path, id and other have been pulled in from other places if that is what you mean by a bastard OS. But those are just utilities. >> What is the name of that UNIX-PC bulletin board somebody mentionned and Yes I am willing to support a number new news feeds for the Unix PC network. >> How long is the warranty? 90 Days on site. >> >> That is a lot of essential questions, and any partial answer is appreciated >> as I am very tempted by the prices..

If you are expecting a MS-DOS style with the base of programs for it, you are out of luck. They are as limited as any other Unix system. >I would maby buy the 3B1, but the 7300's I have been exposed to tent to >disapoint me. They have a bastard child for UNIX.

It is true that the development set is not included. This is also true of the 3b2, 3b5 and up. AT&T has went will selling them separtate. Of course this is true of PC and you get a lot more bang for your buck with the development set and you could trying to buy the same on MS-DOS. >We don't have 3.5 yet, but terminal sessions, and some other functions >lock up from time to time. Usually because of swap space corruption.
