Yes!  Very good point.  If you can't bypass cache then you have
to hope/arrange for re-use, which is much harder.

Subject: How to use two independent monitors from one PC
From: elemjm@ccu1.aukuni.ac.nz (Michael Miles)
Date: Fri, 28 Aug 1992 01:02:46 GMT
Organization: University of Auckland, New Zealand.

I originally posted some questions regarding the independent use of two 
monitors on the same computer. The idea behind this is:
- run a data acquisition program under Windows 3.1 using the colour VGA
  monitor.
- run a separate program (to be written in Turbo C++, Turbo Pacsal 6.0, or
  Turbo Pascal for Windows) to display a small moving object on a different
  monitor, but connected to the same computer.
- a person watching the second monitor, following the object with their eyes,
  has their pupil positions recorded by some A/D board, controlled by the
  acquisition software seen on this first monitor.
- it would be nice if the second monitor was also VGA, to avoid ghosting from
  the moving object.

Solutions so far:
- use a graphics board (complete with software) from 
  a. Colorgraphic Communication Corp, Atlanta, GA
  b. Digiboard
- use a combination of VGA and Hercules monitors + cards, which can be made 
  independent in Windows when running different applications.

I have further questions...
- Are there any other companies which sell these sorts of products?
- What are their postal or phone, fax contact details so I can get in touch 
  with them?
- Has anyone done this sort of thing before - using two independent monitors?
- If so, how?
- What are the names of some data acquisition packages (including A/D board)
  which will run under Windows 3.X?


I will post solutions once I have gathered sufficient information.

Thanks,
Mike Miles.

Subject: TARGA aspect ratio problem w/ LFR Lasergraphics camera
Date: 28 Aug 92 19:48:00 GMT
Organization: SAS Institute Inc.

Hi,
at SAS Institute GmbH of Germany, we have got a LASERGRAPHICS
LFR Plus camera (Matrix Film Recorder) with a RASCOL rasterizing
board.
LFR provides a program called "TRIP" (TARGA Raster Image Printer)
in order to output TARGA images.
They use an aspect ratio of 1:1.0673, and an overscan pixel
aspect ratio of 1:1.2014.
My problem is that when I output TARGA images (converted from GIF
or JPG by Image Alchemy 1.6) to the camera, the images get distorted
with either the normal aspect ratio, even worse with the overscan one.
Is anyone out there who has encountered this problem as well?
Is there a newer release of TRIP than the Release 0.13?
Or, more general, where do these strange aspect ratios come from?
(No possibility to use 1:1?)
Any reference or experience reported to me would be greatly
appreciated.
Regards, 
Thomas

only one program mentioned TIGA (scedit10.zip) and it didn't function

a programming book from TI, "Byte editors chose TIGA as one of 1989's
ten most technologically advanced products."  It's been 3 years and not
much interest for TIGA seem to exist.  Has it been price or some other
reason?  Anyone know.. anyone care?  

I just bought my TIGA this summer and received the TIGA Driver Development

The number of vendors, and the total size of the exhibit floor was
down substantially from recent years, especially if the Showcase area
is not counted.  Vendors pay big bucks for floor space with high
traffic in their target market, resulting in conference profits.  But
SIGGRAPH's income can't help but be down from this aspect of the
conference, relative to other years with more vendors on the floor.
Whatever happened to Genisco, RamTek, Megatek, Adage, etc, etc, etc,....?

I've never been an EC member, but I've been to every SIGGRAPH since
1978, and know some of those folks.  (IMHO) The reason for the big trade show
floor is BECAUSE it brings in bucks.  The reason it is so glitzy is
that the companies are competing for the attention of the attendees,
and that competition has to be eye-catching.

I prefer the SIGGRAPH show floor to other similar shows because
vendors who have been more than once know that there will be some
folks wandering through who will be able to figure out much about
their product by watching demos, and then will ask hard questions.  So
they bring technical people as well as sales droids.  (Sales droids
often get uncomfortable when someone in their audience knows more
about the product than they do, and is willing to tell all, or ask 
embarrassing questions.)

Yes it is a circus, but it is our circus.  It is more overwhelming to
someone new and from outside the community.  The most important part
to me is the chance to interact directly with people I would otherwise
only call or email.  It is big enough now that I never get to spend
enough time with all the people I'd like to.  On the other hand, I always
meet new, interesting people too.  

The motivation for new conferences is (IMHO) (1) to get a smaller, more
focussed group, with a chance to talk with most of the folks present,
(2) to get more good research presented to the community (acceptance
at SIGGRAPH being in the 1 out of 5 or 6 range means at least some good
work doesn't get in, and our journals seem to be excruciatingly slow) 
and the attendant credit to the researchers for doing the work.

As long as the new conferences are self-sustaining, I see no reason
not to create them.  There is some risk, and one role for SIGGRAPH is
to assume some of this risk, while adding expertise to minimize it.

 <jburney.714920310@seamis1> <1992Aug27.123227.1@camins.camosun.bc.ca>

  Sorry not to provide a summary of debate to date, but the 128K 2-way
set associative write back cache module (correct me if I'm wrong about
this KGERMANN) consists of the cache controller chip(s) as well as the
SRAM.  Assuming that (a) the original poster is running windows (or
apparently heavy graphics, re: last post) and (b) the cache system is
zero wait state and (c) that it properly fills the cache via fast page
mode or page interleave, it will significantly impact memory speed over
the internal 8K cache.

  Before you scoff at that 8K cache, it is NOT DIRECT MAPPED, WRITE THROUGH!
That Intel cache is a 4-way set associative, write back cache and is
roughly equivalent to the 64K external caches of most Motherboards!  Of
course, a 128K, 2-way... cache is roughly equivalent to the 256K systems
of many current motherboards.  You can not judge a cache by size alone.
In fact Fevrier@Sunburn presented us with a case in point.  His 256K cache
was just a hair over 20nS cycle time and his 486/50 ran no faster than
a 486/33 with the same cache system due to the wait state.  Ah, but you say
20 nS is zero wait state?  RTFM - there is a delay of a few nS in address
setup time and data latch.  20 nS is a hard & fast cycle time...

   Fevrier - Replace your crystal (50 or 100 MHz) with a 40 or 80 MHz
one.  Your CPU will be slower than at 50MHz but faster than 33 MHz and
the added 5nS per cycle will make that cache zero wait state.  Save the
original crystal for when you upgrade the cache to < 20 nS!

   So, the original point of contention.  What IS the value of this
ZEOS cache system.  Well if ZEOS is single source (they are) and you need
it (you probably do), its worth whatever you will pay.  On a less cynical
note, the chip set, card, connector, etc. is probably worth $120, maybe more.
OTOH, the performance gain is probably more than you would see by adding
4MB without the cache!

I wish Allen Akin and Michael Jones had taken the time to investigate the
direction PLB is taking before making comments.  Rich Thomson is equally
to blame.

1. Yes, the PLB was based on a purely PHIGS model and yes, SGI does not
   care for this model. BUT, there is now two sets of numbers, the
   PLB literal and the PLB optimized where literal is the PHIGS model
   and optimized is whatever you want it to be as long as the picture
   is correct.

2. A good port of PLB takes time (much longer than I or anyone else would
   want).  The chicken and egg syndrome occurs when you as a consumer want
   to use PLB as a required benchmark but its not ready and then the vendors
   see that no one is asking for PLB numbers so they don't spend money to
   work on the port.

3. In a few days (weeks), the reference port, PLB documentation and test
   data will be available for anonymous ftp.  Watch this space and
   comp.benchmarks for more information.

P.S. Allen and Micheal should talk to Keith Seto as should anyone else
interested in SGI's work on PLB.  Keith's number is 415-390-3321.
