- > I would like to here from anyone using SUN computers
- > who can supply answers or comments on any of these issues:
- > Is Franz the only (best) lisp available?
- We have finally finished porting Portable Standard LISP (PSL) to yet
- another machine. This time it is now running on the SUN. Initial
- timing measurements indicate that its speed is somewhere between a
- Vax 750 and 780 (all running PSL), and about twice as fast as Franz running
- the REDUCE algebra system test on Suns. We are now running the Gabriel
- benchmarks to discover where it fits in the set. For more details
- see the announcement at the end of this message.
- > Has anyone used the Maryland Flavors to create useful tools/extensions?
- PSL provides support for a simple flavors package that seems quite
- useful. However, the current version has no inheritance.
- > Any support for sun graphics (windows, menus,etc) a la Interlisp-D?
- We have oload working which allows you to call externally compiled
- routines (like other c sources). So the interface should be easy to
- add (but we haven't done it).
- > Any differential reports of Prolog (Quintus) vs Lisp ?
- None that I know of.
- > Any obvious alternative to SUN? (vendor in same class (Tektronix?))
- PSL also runs on Apollo's and HP Series 200 (both 68K based machines).
- We have also ported a simple "educational" version to the 128K
- Macintosh which is used in a beginning programming class. We plan on
- moving at least the Standard LISP subset and compiler to the 512K mac
- (so if you want to go really cheap...... :-) )
- > Worst or hidden problems, pitfalls, gotcha's, etc.
- We had a lot of problems with the Sun port. Some were hardware
- related, others were differences between Unix 4.2 on the Sun and on the
- Vax. After we get some more experience using PSL on the machine, maybe
- we could report more.
- > > Can real AI development (even applications) be supported on SUN's? <
- I think so, as long as you can get one with enough memory. Some of our
- applications running on HP 9836's (which doesn't have virtual memory)
- really fly (better than a 780 in speed). So, memory is really a key to
- a fast machine.

- PSL 3.2 for the SUN Workstation
-
- We are pleased to announce that Portable Standard LISP (PSL) version
- 3.2 is now available for the Sun workstation. PSL is about the power,
- speed and flavor of Franz LISP or MACLISP, with growing influence
- from Common LISP. It is recognized as an efficient and portable
- LISP implementation with many more capabilities than described in
- the 1979 Standard LISP Report. PSL's main strength is its
- portability across many different systems, including: Vax BSD
- Unix, Vax VMS, Extended Addressing DecSystem-20 Tops-20, Apollo
- DOMAIN Aegis, and HP Series 200. A version for the IBM-370 is in
- beta test and two Cray versions are being used on an experimental
- basis. Since PSL generates very efficient code, it is an ideal
- delivery vehicle for LISP based applications (we can also provide PSL
- reseller licenses for binary only and source distributions).
-
- PSL is distributed for the various systems with executables, all
- sources, an approximately 500 page manual and release notes. The
- release notes describe how to install the system and how to rebuild
- the various modules. We are charging $750 for the Sun version of
- PSL for Commercial Site licenses. Non-profit institutions and all
- other versions of PSL will not be charged a license fee. We are also
- charging a $250 tape distribution fee for each system.
-
- PSL is in heavy use at Utah, and by collaborators at Hewlett-Packard,
- Rand, Stanford, Columbia and over 250 other sites. Many existing
- programs and applications have been adapted to PSL including
- Hearn's REDUCE computer algebra system and GLISP, Novak's object
- oriented LISP dialect. These are available from Hearn and Novak.
