Gilles,

Would you consider the new real-time systems from Hewlett-Packard?  Here is
how it matches your "wish list."

	- SVID and/or POSIX compliant
	  POSIX.1, .4, and .4A compliant.
	- support for Ethernet with TCP/IP
	  Yes.
	- support for the X Window system (at least the client side)
	  including Xlib and all the include files
	  Yes, X11R5 and Motif 1.2.
	- a C compiler with 32-bit int's, with all the C libraries
	  and include files, and "make"
	  The C compiler used for HP-RT applications has been tuned to the
	  PA RISC architecture on which HP-RT and its applications run on.
	- device drivers available for Data Translation and/or other
	  popular high-speed A/D boards (I need an A/D capable of sustained
	  12-bit capture on 16 single ended channels at 10-20 kHz per channel,
	  i.e. an aggregate rate of at least 320 kHz)
	  We are currently working with several VME I/O card vendors.  I
	  believe one of these can help you out.

	I'm hoping this is the proper forum for this discussion.  My 
sincere apologies if it isn't.  Since I couldn't find any Lynx-specific 
newsgroups, I thought I'd give this one a whirl.  
	Our department is looking to move future development away from
the old Versados workhorse onto something new, with support for current
(and hopes for future) hardware.  We run straight off of MVME-1XX's 
(currently 147's).  We have worked with PSOS, and are now considering 
an evaluation of LynxOS.  I was looking for experiences--both good and 
bad--that people on the net have had with LynxOS.  To save net resources,
please e-mail me.  If there's interest, I'll post the results I get.
Thanks in advance for all help offered.

Subject: Looking for a real-time UNIX for the 486
Organization: University of Manitoba, Winnipeg, Canada
Date: Fri, 11 Dec 1992 18:20:33 GMT

Hi, folks.  Sorry if I'm asking something that's come up here before, but I
rarely get a chance to read this group (nor most other groups for that matter.)
I'm looking for a low-cost, real-time UNIX system - preferably one that will
run on an AT-clone 486 machine.

I've developed about 80,000 lines of C code on Masscomp/Concurrent systems,
to do A/D capture and analysis.  I recently ported the graphics side of my
code to the X Window system.  I'm now hunting around for a more affordable
replacement for the Concurrent machines, without requiring a major rewrite
of my software.  Here's my Christmas wish list for such a system:

	- SVID and/or POSIX compliant
	- support for Ethernet with TCP/IP
	- support for the X Window system (at least the client side)
	  including Xlib and all the include files
	- a C compiler with 32-bit int's, with all the C libraries
	  and include files, and "make"
	- device drivers available for Data Translation and/or other
	  popular high-speed A/D boards (I need an A/D capable of sustained
	  12-bit capture on 16 single ended channels at 10-20 kHz per channel,
	  i.e. an aggregate rate of at least 320 kHz)

I realise I'll need a high-speed, 16-bit SCSI controller to store data to
disk at that rate, but I also need an operating system that can handle it.

From what I've heard so far, the soon-to-be-released POSIX compliant version
of QNX will address all these requirements, except maybe the device driver.
I'll be contacting Quantum Software for more details.  I've also been given
the impression that LynxOS will address these needs, but I don't know who
to contact for more information.  I'd also like to find out if there are
other, more suitable systems out there, and who I should contact for details.

If anyone has any information, leads, words of wisdom, etc. on this, I'd be
glad to hear it.  Replies by e-mail are preferred, but I'll try to browse this
group more regularly.  Thanks.

Having done  this once before for a small college, I have several
suggestions.  First off, buy real clones, i.e., build them yourself out
of name brand components.  Second, have a custom logo made to put on
cases, monitors, and keyboards.  This will give your product name
recognition.  Thirdly, spare up all the really important parts, such as
drives, cards, monitors, keyboards, power supplies, and motherboards.
Finally, only have two PC models, cheap and great.  For the cheap model,
a 4 meg ram vga SX 386 25 or so would be right and should cost about
$1,100 to $1,200 in a reasonable quantity.  The great should be a 486
with superVGA, local bus video, 8 megs of RAM, and a 200 meg drive.  It
should cost about $1,900 or so in quantity.  In terms of printers, my
advice is to stick with a cheap Epson, like the LQ 570, which has
scalable fonts and 24 pins and prints beautifully, or to go to Laser
printers, such as the HP 3P.  For an intermediate solution, pick an HP
Deskjet 500 B&W.

Thus, you deliver two systems, cheap and great, and three printers.  All
of these can be had at the right prices.  Make sure that you private
label your pcs and spare up.  The only thing left to consider is who
will do the maintenance.  You give 1 year P&L and then charge a fee for
maintenance, something like $30 per hour for labor plus parts costs, and
then that's it.  

Curiously, if you purchase lots of such gear for university use, the
savings can just about pay for a full time technician.  At WIU, we did
exactly that, and quickly got away from Zenith and IBM to real clones,
saving at least 25% per machine in the process.

This is interesting but becoming somewhat off topic for comp.admin.policy.
There is a newsgroup which is chartered to cover topics specifically like

i am not a funder, fundee, and probably not capable of being either, but
this struck me as wrong.

if i, as a large corporation, provided a grant to your department, to do
research on a specific thing, i would get real pissed to find out that what
i have given you is now being used all over the campus, without my knowing it.

i think that before the Dean gives authority for anyone, other than those
deemed in the funding papers, access, the dean should inform/get authority
for that funding to be used by any other department/project.

you could work this backwards, and find out what reaction the funder has
when they learn the total lack of respect the dean has for their funding.

This sounds like a good approach, but there are a few things to consider:

The folks who currently have strong opinions on computer needs may not
be representative of the population of computer users five years hence.
If you're trying to put together a long-term plan, you should make a
strong effort to contact folks who don't use computers much now.

If you do a mass mailing electronically, you will get responses only
from those who are comfortable with electronic communications.  Make
sure to poll folks in several ways (via email, paper mail, conversations
in the department lounge, and so on).

Find out what people need to do, not what they think you should buy.
Users, by and large, are not experts on current and future information
technology.  They are, however, experts on the kinds of work that they
do.  Take advantage of that!  A user who only does light word processing
doesn't want an RS/6000, no matter what Prof. Hornswoggle told them.  And
a user who does only FORTRAN number-crunching probably doesn't want a 
Mac.  Use your knowledge to match user needs to the right hardware and
software, and things will have a much happier ending.


Good luck with your survey!  And please keep us posted on it.


William

Well, IMHO your chairman and deam are thoroughly and obviously wrong.
In fact, the very assertion that someone can use resources you
obtained with grant money /without your permission/ seems completely
ludicrous.  In the case of computer systems, for example, if you do
not give them explicit access (say in the form of a user account) an
attempt on their part to use the system would constitute a break-in
attempt (electronic tresspass, a federal crime in the US... call the
Secret Service).  In the case of software, there might even be
restrictions on whom you /can/ give permission to use the software,
since you might have a license agreement that restricts who can use
the software.

Furthermore, if your institution does not have a written policy in
this regard (that you signed!), then any software written by you is
your property and your property alone.  (The author of any work
automatically has copyright ownership in most countries including the
US, unless he/she explicitly renounced such rights.)  If your work
involves porting someone elses software, then it is a derivative work,
and as such that portion that makes the work derivative is yours, i.e.
you don't own the original software, but have full and sole ownership
of the modifications that were necessary to port the software.  It is
important to note here that many academic institutions require their
faculty, staff, and students to sign a document that gives the
institution copyright ownership of any work that is produced using the
institution's resources, but if you did not sign any such document
your work is yours.

If they claim otherwise, sue them.  ;-)

Traditionally, however, academic employees own the rights to journal 
articles and textbooks that they right while employed by a University,
even though publishing these is consider a prerequisite for tenure and
promotion.  In fact, professors frequently write class notes, teach
from them, and later publish the notes as a textbook.  Even though 
they were originally created for a class (and teaching is clearly 
within the scope of a professor's duties), universities claim no rights.

This is probably a matter of tradition, not law, and might very well
not carry over into software, although I know professors who have
published software and don't give any portion of the royalties to their
employers.
