The Cambridge compiler is now distributed by the following company:

Qudos Limited
Unit 2
Cambridge Science Park
Milton Road
Cambridge CB4 4FD
England
(0223) 862333
Telex:  818114
Fax: 862946

Since it is now a commercial product, presumably it comes with a
reasonable amount of support.  I don't know the price; perhaps
someone else will post it.

The only other VAX/UNIX compiler I know of (other than Powell's)
is a beta-test version from Tartan Laboratories.  They offered it to
universities last year for a reasonably small fee, but when I talked to
them this spring they had discontinued the offer for lack of interest.
If you would like to see this compiler made available, you should let
them know.  Contact Scott Wilson at the following address:

Tartan Laboratories, Inc.
461 Melwood Avenue
Pittsburgh, PA  15213
(412) 621-2210

Incidentally, those who use Powell's compiler should be aware
that the language it compiles deviates in many respects from the
language described in Wirth's _Programming in Modula-2_.  Some
of the discussions I have seen lately in this newsgroup stem
from users of the Powell compiler complaining that other compilers
don't behave the same way it does.  Users of this compiler should
note that it does _not_ define Modula-2.  I am not criticizing
Powell's compiler; it has many attractive features.  However,
unlike many other compilers, it was written from scratch rather than
being a modified version of an ETH compiler.  As a result, Powell
often interpreted language issues differently than other compiler
writers.  He also added a number of extensions that other compilers
do not support.
