The "upgrade" was, in actuality, a trade-in program.  I don't know if it
was even offered outside the U.S..  Pricing in the U.S. was such that it
made more sense to sell the 500 and buy a new 500C, anyway (at least in
my mind).  The same reasoning probably applies in Germany.

You didn't say in your original posting, but do you have the JetDirect
for unix option?  (C2059T card w/ associated software)  If so, then look
in the /usr/lib/hpnp/examples2/hpnp.ctrl.ps directory for examples on
PostScript duplexing.  Look in the /usr/lib/hpnp/examples2/hpnp.ctrl
directory for examples on PCL duplexing.  If you don't have the C2059T
card, ask someone who does for duplexing examples.

Summary: how to print a 'watermark' on a page?
Organization: Tate Enterprises
Date: Sat, 7 Nov 1992 20:10:30 GMT

I would like to print a 'watermark' on every page of printout on my
LJ-III. By watermark, I mean something like printing DRAFT in large
char's in the middle of the page in a gray filled char. set. I have
gotten the LJ3 to print the word that way, but I can't get it to go back
an print the listing over it. I think that a macro should make it
automaticly work for every page (from the description in the manuals),
but haven't found the magic sequence to use to print.

I would like to be able to just down load this to the printer when needed
so I don't have to be dependent on any one wordprocessor /editor /*roff
/etc. I don't have PostScript (I have seen this done with it), just the
PCL5.

Just a short comment:

SCSI is used very much and there is nothing wrong with SCSI itself.

The problem is that, even though SCSI has been on the market for 5-10 years,
the compnies producing SCSI peripherials does not follow the SCSI specs. Or
the specs. are to "lose".

In the "good old dayes" when ST506/412 was used you knew that if you had a
ST506/412 controller it for shure would run with a ST506/412 disk.

With SCSI one can be shure that if the computer can run with one type of
SCSI disks it can't run with others.

So my advise is that you should avoid SCSI as far as possible, but as it is
"in" I'm not shure you can get very many peripheriasls without SCSI.

Hi,
I am porting an application that requires very fine
timing control to Solaris 2.0/2.1. I need to be able to schedule
my program at given time increments. The time increment can be
anywhere from 1 millisecond to 50 milliseconds. I gave played
with setitimer and SIGALRM , they do work fine except I can not
get better than 10 millisecond granularity. So I decided
to try something more hardware oriented and noticed that there are
2 timer/counters in the MMU chip.
Questions:

1) Does the OS use either or both of these counters?
2) Are there other timers available on the Sparc platform?
3) Does the equation change if I use a VME based SparcEngine?
4) Does/Has anybody done/? any work in this area and give me some
   pointers?
5) Are there other calls in Solaris 2.0 and derivatives that would
   allow me to what I am trying to do ????

Thanx for any and all answers/pointers/criticism/etc...

Subject: Searching feedback on realtime OS

Organization: Soft*Star s.r.l, Torino, Italy

As the subject states I'm looking for some feedback on realtime OSes.

I've been looking around on the market and found quite a bit of
realtime OS; as usual all the literature is biased and the main
difference between the objects is price. As you can imagine I cannot
afford to try them out all due to time and monetary constraints.

I have focused on the following OS:

	OS/9, LynxOS, pSOS, VxWorks

and a bit less on VRTX. My preference will go to all those OSes
that have a Un*x like programming interface so that applications
can be developed on our Suns without having to learn a new API.

The hardware platform is unknown and can be a 486 PC using LynxOS
or a 68xxx VME; I personally prefer this last choice for reliability
and expandibility but it could be overridden by it's cost.

The whole `thing' will be used to process around 20 analog channels
that carry info from pressure sensor and thermocouples; the maximum
sample rate should be less than 10KHz.

If you have used any of the mentioned Oses or know of others I missed
and are willing to share your knowledge please do.

I'll post a summary of my findings.

Just a last note, since I have a terribly unreliable news feed please
CC: your answers to eb@icnucevx.cnuce.cnr.it.

Thank you

I believe that there is a public domain device driver for OS/2 2.0 that

Probably true. Also I'd advise you not to use the workplace shell. Use

the workplace shell tends to be high overhead, deadlocks easily and is
basically not reliable or consistent (for real time work).

I am turning to the net for career advice.  This message is not
soliciting jobs (though I would be glad to hear of any) and thus, I
hope, will not be considered _too_ inappropriate.

I am graduating this December with a MSE in Systems Engineering.  I have
concentrated in two areas throughout my academic career: real-time control 
and manufacturing.  In beginning my job search I have found that, due to my 
past experience and degree, I tend to be slotted into the "MIS" programming 
field, an outcome which I most emphatically do not desire.

Therefore, I have decided that I must take my case directly to companies, 
rather than depending on on-campus recruiting or personnel offices.  I need
suggestions as to what industries and specific companies could use my talents.
I am restricted to the Philadelphia Metro area., including S. Jersey & 
N. Delaware.

If anyone could give me a few pieces of advice, or would be willing to
electronically discuss my situation, please respond to this post to:

green@eniac.seas.upenn.edu

If you have a few tidbits of information but don't have the time to discuss
them, I understand.  Just send along what you can and put a note at the 
bottom which say "no time to discuss", or somethins similar.  Any feedback at
all will be useful to me.

This is probably overkill, but the Motorola MC68302 supports SDLC, with
the following exception (quote from the User's Manual):

    SDLC is fully supported, but the SDLC loop mode (ring
    configuration) is not supported.

The '302 has an M68000 core with 32-bit registers and 16-bit data paths
(internally and externally) and some intelligent peripherals integrated
into the chip.  These include 3 independent full-duplex serial
communication controllers which provide the SDLC support plus several

I've used their PC bus card using a National Semiconductor LM629.

the LM629 was better. But the biggest drawback of the LM629 was that it's
