A friend at Symbolics told me that a comprehensive language project is
going on there; by the time the new machine is released, they expect
to have C, Pascal, and Fortran 77 (translated to Lisp, of course.)
Since routines in any of the languages will be mutually compatible,
they will be able to provide the same whizzy program development
environment that is already there for Lisp.

Also, in response to the question about network support, they seem
biased towards chaosnet, but may be swayed by their customers' needs.
They may even talk TCP/IP soon.

I would appreciate any info on available C compilers and optimizers
for the 68000. I have heard rumors that the MIT compiler is 'better'
than Whitesmith's and would like to hear other comments. Please send
replies to milunovic@sri-kl and I will send a combined response to
Works. Thanks.

Subject: MC68000 Paging Query

I have a report from John Gilmore, an independent consultant, which
has info on this problem.  In brief, he states that:
	1.  On a page fault, the executing instruction can not in
            general be identified.
	2.  There is no way to determine how far execution of the
            instruction had progressed prior to the pafge fault.
	3.  Any executing instruction is aborted when a page fault
            occurs due to instruction prefetch.

His report is titled "Suggested Enhancements to the Motorola MC68000"
and is 14 pages long.  The report is copyrighted, but may be
reproduced if not for commercial advantage and credit for the source
is given.  His address is:

Hope this is of some use to you.

Luckily, LISP has a much larger semantic space than most languages so
it is much easier to imbed a C, PASCAL, FORTRAN or whatever language
you wish to program into it than the other way around.  I would not be
surprised if someone hacked up a PASCAL, ADA or FORTRAN front end for
the LISP machine which just transformed the source program into LISP
program and passed it to the compiler.  I am less sure that someone
would be interested in doing this for C.

The SUN sounds wonderful, if you're willing to spend $5-7K each for
them (which is reasonable in some industrial environments, but I find
it farfetched that a University would spend that kind of money on its
students for instruction) and if you don't want to work at home.

Couldn't you put a couple floppies and a modem on one of these things
and make it usable over a dialup?  If you're already spending $5K,
another $1500 seems insignificant for the extra capability.
