Subject: VAX Interlisp Availability
In response to the Silverman [V1 #7] message:
Interlisp is available for both the VMS and UNIX operating systems for
the VAX family. For more information send a note to Interlisp@ISIB
with a post office address in it.

Subject: LIPS
[Reprinted from the Prolog Digest.]
The LIPS (logical inferences per sec.) measure for Prolog (and maybe
other logic programming systems) is not as useless as it might appear
at first sight. Of course, resolving a goal against a clause head
takes a different amount of work for different goals and clauses, but
a similar observation could be made about the MIPS measure for
conventional machines. The speed of the concatenate loop
conc([],L,L).
conc([X|L1],L2,[X|L3]) :- conc(L1,L2,L3).
appears to be a remarkably good indicator of the speed of a Prolog
implementation for large "pure" Prolog programs (ie. Horn clauses+cut
but no evaluable predicates except maybe arithmetic). For example,
compiled Prolog on a DEC 2060 runs at 43000 LIPS with this estimate,
and (interpreted) C-Prolog on a VAX 11/780 runs at 1500 LIPS. Prolog
compilers for the VAX and similar machines are starting to be
developed, and at least one is expected to reach 15000 LIPS on a VAX
780 (it will be quite a while before these are incorporated into full
Prolog systems). The first Prolog machine prototype from Japan (the
Psi machine from ICOT) is expected to reach 40000 LIPS.
Extensive use of evaluable predicates may invalidate the measure to a
large extent (but then, we aren't talking about *logic* programs
anymore, and "logical inference" is no longer the main operation).

Subject: Kurzweil Reading Machine
The Kurzweil company, a subsidiary of Xerox, is producing a reading
machine which is, to my knowledge, the most advanced in the industry.
Xerox had the unit on display at the NCC in Anaheim in May.
Xerox has recently donated a number of the Kurzweil units to various
educational institutes to aid blind students, so some people on the
nets have probably had experience with them or can locate one nearby
to check out.

Ken (and everyone else!),
Thanks for the response to my cry for help [concerning expert
systems for evaluation at RADC]. From 9 Jun thru 20 Jun I will be
enjoying "God's Country" (Oregon to the uninformed). But, until my
storage quota is exceeded, my mailbox will accept msgs--which I will
dilligently answer on my return.
For those of you who don't know me personally, I was a chemist
before being "lured" away to the US Air Force and electronics. I
still maintain my ACS membership (American Chemical Society). C&E
News (the ACS weekly info publication) devoted a large part of their 9
May 83 issue to computers and mathematical tools and their influence
on Chemistry. Their "Special Report" feature was entitled "A computer
program for organic synthesis". I have not studied it, but have
skimmed it, thinking it would be worth reading.
I have just received my 30 May issue, and its "Special Report"
feature is entitled "Troubled Times for Scientific Journals", which
should be of interest to those of us who do (or must) publish. (Only
a small section on Electronic Publishing.)
Those interested in reprints of either special report can send
$3.00 for each report (although 10 or more cys of one report are only
$1.75 each). Requests are sent to: Distribution, Room 210, American
Chemical Society, 1155--16th St., N.W., Washington, D.C. 20036. They
want prepayment for orders less than or equal to $20.
For those of you who are fans of Asimov's robot novels/stories,
the article "Molecular Electronic Devices Offer Challenging Goal"
might be one way of accomplishing the "positronic brain".?! (This,
too, was in C&E News, but the 23 May issue...yes, C&E News is not my
highest reading priority--note the dates.)
Thanks again for all your help.
