-
- 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.
