It depends on what pdp-11.  You'll need to supply more info.

What's the betting Steve gets to tell us all why 2.11 BSD won't run on a 
/23 or /34.... again....

(Hi Steve!)

If there's ever a FAQ written for this group/list, that question's gotta 
go at the top.

Speaking of 2.11!!  Now that USL is going to become a subsidiary of NOVELL
rather than AT&T, I wonder if there is any chance we could convince them
to waive the need for a UNIX license for this old a version??  Kind of like
what I understand DEC (thru DECUS) has done on PDP-11 OSes in OZ.
I can't imagine they are planning on supporting UNIVEL on the PDP family of
machines.  I would guess that the largest number of PDP's are now in the hands
of schools and hobbyists where they do not provide any kind of a market.

Comments??

	Ok, i will ;-)

	There is Unix available for the PDP-11.  2.11BSD is being distributed
	by the USENIX Association and requires a Unix source license.  Not
	all models of the PDP-11 can run 2.11BSD.  There are four major
	requirements:  1) split I/D, 2) supervisor mode (the 4.3BSD networking
	code was moved out of the kernel into supervisor), 3) at least 1mb
	of memory (it can fit in less but it's unhappy about it) and 4) hardware
	floating point (there is an emulator but it doesn't work at present).
	To load the entire distribution requires at least 80mb of disc space,
	more is better.

	Requirement #1 is the most restrictive and leaves out the 11/23, 11/23+,
	11/24, 11/34, 11/40 and 11/60.  The 11/45, which has split I/D and
	supervisor, can not support enough main memory (hard to load a system
	which takes 320kb into 248kb :-)).  Models which run 2.11BSD very
	nicely are the 11/44, 11/53, 11/70, 11/73, 11/83, 11/84, 11/93 and
	the 11/94.  

	From the mess i call a home directory hierarchy i dredge this notice:


	"Yes, there is UNIX available for the pdp-11/73.

	Yes, it is 4.3BSD, or as close as you're going to get on a pdp-11
	(basically the only syscall left out was swapon()).  Full tcp/ip
	(with the Jacobson slow-start, etc, etc), 4.3 disc quotas (if you
	want 'em), and so on.

	To get your copy of 2.11BSD contact the USENIX Association:

		2.11BSD
		USENIX Association
		2560 Ninth Street, Suite 215
		Berkeley CA 94710
		+1 510 528 8640

	Price is $200, includes source (so you will need a source license),
	2 1600BPI tapes or 1 TK50 full of stuff.  "support"?  well, drop me 
	a mail item - the care and feeding of 2.11BSD has more or less been
	delegated to me."

	Updates and patches are available via anonymous FTP to the host
	WLV.IIPO.GTEGSC.COM [192.26.147.1] in the directory pub/2.11BSD.

  Unfortunately, I doubt USL thinks that way. For one thing, much of the code
in 2.11 is 4.3-derived (or at least 4.3-inspired). Given the fuss that USL is
making over the Net-2 release, I can't see them agreeing to this.

  On the other hand, it _would_ be nice if they dropped the Net-2 suit and
let us have a free PDP-11 Unix...
