I wrote a program that gets Adobe Font Metrics (AFM) files from any PostScript
device, and I have posted it to net.sources. I attempted posting this program
some time ago but it was redirected to /dev/null at an upstream site, as was
all outgoing news from Swarthmore College. You should check it out, and
E-Mail me if it is useful to you. The last time I posted to net.sources, I
also posted notices like this on mod.computers.laser-printers and, I believe,
comp.graphics and I received several requests for the program, called getafm.
I have fixed some bugs and now it works fine for teaching your computer to
ptroff and enscript in fonts that you have on your PS device but have no
AFM files for.

Subject: PC graphics cards/standards/monitors

I have just started looking at all these graphics cards for PC's (we have
zeniths with IBM cards here at Queens)  and am frankly getting quite confused
about all the different standards (CGA, EGA, HERC, ...the new IBM standard)
as well as what screen works with what (monochrome, high-res, ttl...)

I have some vendor documentation but it's difficult to see the forest for the

simple overview of the whole subject of graphics cards/standards/monitors?

Please send any mail to me,  I will forward a list of responses

A 3 board set from ADAC (Mass. company, check advertiser index in

A programmable clock board, also from ADAC.

A small plotting scope (Hewlett-Packard 1350 I think).

We chose the ADAC boards because they were they only ones which offered
DMA-driven DAC's.  With DMA, we could plot points at about 10 usec /point.
Animated displays consisting of ~512 points per frame could easily
be displayed at 100 Hz, with higher refresh rates possible as the

Bay Area ACM/SIGGRAPH and SIGBIG present:
"A Quick Introduction to Vector and Parallel Processors for Graphics
Programmers"

Speaker: Richard Friedman
Sr. Systems Analyst, Pacific-Sierra Research

Do you believe in the Desktop Cray?  Computer graphics is extremely
compute intensive, hence frequent use of supercomputers.  Many such
features are finding their way into smaller mini-supercomputers, main
frames, and now personal computers.  In the not too distant future, we
will see the day of the "Desktop Cray."  The question is not "if" but
"when?"  We have invited our speaker to give us a glimpse into the future.

Topic:
Richard Friedman will give us a quick tour thru today's
"supercomputers," along with the joys and difficulties of programming
them for real applications.  To utilize these machines both easy and
radical changes in coding styles are required.  He will address the
questions: "What is vectorization?" "How do you program for parallel
execution?" and "What about portability?" among others.

About the Speaker:
Mr. Friedman started working with state-of-the-art supercomputers (CDC
6600) in 1965 at the Courant Institue of New York Univ.  From 1968 to
1981, he was in charge of programming languages and libraries (CDC 6600
and 7600) at the Lawrence Berkeley Laboratory of UC Berkeley.  He spent
1977 at the European Weather Centre (ECMWF) in England which was one of
the early Cray-1 sites. Since joining Pacific-Sierra Research, Mr.
Friedman has created special applications software for the Cray and
Cyber-205 systems and has been involved with development on Alliant,
SCS, and other supercomputer systems.

                     Call for Contributions to a Workshop

                   HIGHER LEVEL TOOLS FOR WINDOW MANAGEMENT


22nd - 24th August 1987, Amsterdam, The Netherlands.


Scope/Aim

The past few years has seen the proliferation of window managers and software
using them. They now form an integral part of the software available on many
general purpose workstations. These window managers differ in their conceptual
models, the facilities offered to the application programmer, and the
facilities offered to the user for managing the display. In the light of
experience, progress is being made toward resolving these differences. 

This workshop will examine questions that relate to more powerful tools, both
for the user and for the programmer.  Questions to be considered are: 

  When and how should windows be used?
    One per application, to permit multi-tasking?
    Many per application, to permit a more expressive interface?
    What alternative paradigms could be used instead?
  
  What policy-making tools can be provided to ease the burden on the user?
    What automation of screen layout is desirable?  
    How much tailorability (by the user) is really useful

  What tools can be provided to assist the application programmer?
    What tools are required to simplify the programming of presentation,
      interaction and feedback?
    Can higher levels of abstraction be provided which satisfy a range of 
      application domains?
    Can good interaction styles be provided using a range of input devices?

  What are the performance and portability requirements?

Workshop plan

Contributions which address one or more of these questions are solicited. The
workshop will occupy three days, evenly divided into presentations and
discussions. Up to 10 invited papers and 10 refereed papers will be presented.
Working group discussions will be held on selected topics, and the outcome
reported to plenary sessions. Participants will be limited to approximately 50.
It is intended that the workshop proceedings be published. Speakers will be
given the opportunity to revise their papers before publication

                                THE GKS REVIEW

26th and 27th September, 1987, Moorside Hotel, Disley, Manchester, U.K.

Scope/Aim

GKS became an international standard in 1985. A number of implementations now
exist and are in constant use. The working group on computer graphics within
the International Organisation for Standardisation (ISO TC97/SC21/WG2) has
asked its member bodies to look to a review of GKS. The workshop will
investigate the following questions: 

  Which features of GKS are good?
  What are the deficiencie of GKS?
  Is there a need for a minimal GKS?
  What should be added to GKS?
  When should GKS be modified?

What attempt should be made to restrict the changes to GKS both in this and
future revisions. Should certain features be labelled as 'deprecated' - a
candidate for possible removal in a future revision as for Fortran 8X. 


This workshop is being organised in conjunction with the BSI Graphics Panel
(BSI IST/21/2). Participation is NOT restricted to UK residents. Participants
will be selected on the basis of submitted position papers. 

Workshop plan

Contributions which address one or more of these questions are solicited. The
workshop will occupy two days, evenly divided into presentations and

I'll be deeply indebted to any person who can provide me with the following
information.

I am restoring a vintage-1974 Digital Equipment Corporation PDP-11 based
graphics system, including the following components:

  Digital PDP-11/10 (`decgraphic 11/10')
  CalComp 565 plotter
  Teletype 33 TU (ASR) hardcopy terminal
  Digital VT05 video terminal
  Digital VT50 video terminal
  VT11 graphics co-processor
  GT42 display scope

I am looking for parts sources for all of these components.  Among other
things, I need connectors and cables, a light pen for the GT42, several
parts for the terminals (in fact, I'd like to find junk terminals to scrap
for parts), and accessories for the plotter.

Do you know of another `decgraphic' system?  Do you know of _software_ for
a `decgraphic' system?

Also, I'd love to hear from you if you are interested in `antique'
equipment.

Please reply to me directly, as I am not on INFO-GRAPHICS, INFO-HAMS,

compute intensive, hence frequent use of supercomputers.  Many such
features are finding their way into smaller mini-supercomputers, main
frames, and now personal computers.  In the not too distant future, we
will see the day of the "Desktop Cray."  The question is not "if" but
"when?"  We have invited our speaker to give us a glimpse into the future.

Topic:
Richard Friedman will give us a quick tour thru today's
"supercomputers," along with the joys and difficulties of programming
them for real applications.  To utilize these machines both easy and
radical changes in coding styles are required.  He will address the
questions: "What is vectorization?" "How do you program for parallel
execution?" and "What about portability?" among others.

About the Speaker:
Mr. Friedman started working with state-of-the-art supercomputers (CDC
6600) in 1965 at the Courant Institue of New York Univ.  From 1968 to
1981, he was in charge of programming languages and libraries (CDC 6600
and 7600) at the Lawrence Berkeley Laboratory of UC Berkeley.  He spent
1977 at the European Weather Centre (ECMWF) in England which was one of
the early Cray-1 sites. Since joining Pacific-Sierra Research, Mr.
Friedman has created special applications software for the Cray and
Cyber-205 systems and has been involved with development on Alliant,
SCS, and other supercomputer systems.

Subject: SURFMODL 1.1 available

SURFMODL (surface/solids modeling program for the IBM PC and compatibles)
version 1.1 is now available from Simtel-20. It is broken into two
archives; the first contains the full source code (4000+ lines of Turbo
Pascal code), documentation, and example data files.  The second contains
several different versions of the executable code to support the Hercules
graphics board, CGA, EGA, Heath/Zenith Z-100, AT&T 6300, Sanyo MBC-55x, and
IBM 3270.  You will need the following two files:

Filename            Type     Bytes     CRC

Directory PD:<MSDOS.SURFMODL>
SURFMODL.ARC            BINARY    234507  F713H
SURFMVSN.ARC            BINARY    346348  5759H
