[net.lang.st80] Smalltalk implementation on Sun's

tomi@mcvax.uucp (Tetsuo Tomiyama) (10/24/86)

We are very much interested in Smalltalk-80 implementation for
Sun-2/3s.  We know there is an implementation from Berkley and we would
like to know its performance, goodies, etc., from somebody who are
using it.

I have also read on the net that Xerox has started distributing
Smalltalk for Sun's.  Is there anyone over the net who have any
information about this?  (Price, applicable machines, conditions of
license, contact address, etc.)

As usual, if I received many reactions, I will summarize.

Here at UNC we have used both the Berkeley and Xerox PS
interpreters, and on both sun-2's and sun-3's.  I would judge the
performance as follows:

    Berkeley ("bs")
        Sun-2	barely tolerable
	Sun-3	reasonable

    Xerox PS
	Sun-2	reasonable
	Sun-3	excellent

To be fair to Berkeley Smalltalk, I would say that it is better
integrated into Unix (uses Unix new lines, unlike Xerox PS which
uses carriage returns), and is in some sense a better experimental
tool since the interpreter source code is available.  (We do not
have source code for the Xerox PS interpreter here at UNC, although
I suppose some sites do.)

Since we have gone through the exercise here of getting around
various shortcomings in the Xerox PS interpreter, I was planning on
posting some bug fixes and goodies to the net.  Is anyone out there
interested, or will I just be wasting my time?

cheers,

Tim Rentsch

We're interested.

I'm interested....

I'm interested, too.  I've tried to tackle the newline problem in PS once,
but was not very successful (destroyed a working image accidentally).
I also don't know which would be the right place to translate CR to LF and
vice versa (I don't have access to BS at the moment, so I can't look at that).
If anyone has a solution, please send mail or post!
