Today's Topics: LiSP Machines - Not Just for LiSP MC68000 Query - Answered Hardware and Editor Technology ----------------------------------------------------------------------

Date: 28 Oct 1981 11:03:57-PST From: ARPAVAX.ecc at Berkeley Full-name: Eric C. Cooper Subject: Languages and Lisp Machines

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.

Date: 28 Oct 1981 16:00:37-PST From: ihnss!ihuxq!ihuxp!ljspot at Berkeley 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: 431 Ashbury St San Francisco, CA 94117 Voice: (415) 621-9355 ABBS(300 baud): (415) 863-4703

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.
