[net.unix] HELP - Cheap form of UN*X wanted for PDP

phaedrus@eneevax.UUCP (06/13/84)

REQUEST 1

	There was an article regarding some form of UN*X for the PDP-11/73
distributed by DECUS, awhile back.  At that time it did not interest me
so I didn't save it.  If somebody has it out there in net-land could you
please mail it to me?

REQUEST 2

	I am working for a very small software firm and we just got a
PDP-11/73 running RSX-11.  If anyone knows anything about a *CHEAP* UN*X
(especially if sombody like DECUS is selling it) please send me all the
info that you have.

It is difficult to move from a VAX-11/780 running 4.1bsd to a pdp running
rsx, so have mercy and HELP ME please.

				Thanks a billion IA (in advance)

No -- there isn't any such thing as a cheap form of Unix.  What you
are probably remembering is the DECUS C system, which is a set of
public domain software including a compiler, several libraries,
and lots of familiar utilities.  This software runs on many DEC
operating systems, including RT-11, RSX, RT emulated on RSTS, RT
emulated on VMS, others I can't think of offhand.  It's available
as DECUS 11-SP-18, second (1983) release, for the cost of reproduction.

Back before DEC started licensing Ultrix and V7M-11, they had a cheap
Unix distribution, but you had to have an expensive Bell license first.

You can get a binary license for UNIX on the PDP-11/73 from DEC
but NOT from DECUS.  DECUS does have a C compiler for RSX though.
The DEC PDP-11 UNIX product used to be called something like
UNIX V7M-11 but the name may have been changed to ULTRIX-11.

You may be able to sublicense UNIX from an OEM, although they
usually want to sell you the hardware too.

There are some UNIX "look-alikes" available, and one of these may
keep you happy.  Every so often they are reviewed in one of the
glossy UNIX trade magazines.  I hesitate to mention any since I
may well inadvertently leave some out, but I will mention that the
first UNIX look-alike commercially available seems to have been
Whitesmith's IDRIS.
