Obviously you have been talking to SUN groupies :-)  In case you
haven't heard, the SUNos is now also SYSV UNIX, just like HP-UX.  It
also now has all the warts like SYSV.  It took SUN a few lost
government contracts to switch over to the more standard SYSV.  As
far as I can tell, (I admin both), both machines are equally
reliable.

The SUN does have two major faults, both of wich will affect you in
the educational field.  First, the window system is very buggy.
The well know bug in OpenLook is to 1) start several windows from the
window manager pull-down 2) move the first window before the other
windows appear and HOLD THE MOUSE DOWN.  3) Presto, the window
manager locks up!  The only way to restart the display is to kill
all the X processes and then manually reload the color map (white on
white does not afford a good login chance :-) ).

Of course, the SUN doesn't have an X login screen as shipped, so
users will be confused from the start....

Usually, our scientists use our HP X Terminal instead of the SUN
console because 1) it can be rebooted when SUNos locks up and 
2) the screen is bigger :-)

Of course, sometimes OpenLook just quits.  Try to dump a window from
a SUN from a remote computer.  Poof!  OpenLook failure!  (This is
fun, especially on a University net! :-)

Second, the SUN can be halted from the keyboard!  Try pressing L1-A
on your next demo trip.  Relocating the CPU with a monitor extension
cable can't take your workstation out of prying student fingertips
like the  HP can...

Of course, the HP window system has problems.  Mostly this is a
result of over-use of system RAM.  A vaunted part of HP-UX 9.0 is
"VUE-lite" which should solve this problem (we'll see :-)

Finally, a last point:  in a network of Suns, HPs, and SGIs, I
always hang the printers, tape drives, and other services off the
HP.  I like that the HP software always works the same way.  If it's
broken, it's broken EVERY time.  I don't have time for the
intermittent failures of the other two OSs...

I figured how to connect an HP 97560 1.3 GByte disk to an 9000/817 running
hpux-8.02. It was a *horrible* hack, and included editing the kernel /hp-ux.
But it worked, and we've been using the disks for several months without any
problems.

I posted this before, but if anyone's interested I can explain the trickery
once more...

After you make conf.h, you must edit it by hand so that has_mmap is 0.
This works around an HP-UX 8.07 kernel bug that could be causing your problems.
I've heard that the bug is also fixed by HP patch PHKL_0942.

Once you fix this, you'll probably get another bogus warning
``Traditional diff is used, so RCS is limited to text files''.
This warning is caused by a bug in HP-UX 8.07 `tr'; the command
	tr '\012' '\200'
deletes newlines instead of transliterating them.  Ignore the warning.


>#warning: diff -c does not work, so diagnostics may be cryptic

That warning is caused by a bug in HP-UX 8.07 `sh'.
The following patch to rcstest works around the bug.

But, in my experience, the flicker/waver on another nearby monitor is
not entirely due to power fluctuations, but is more due to that "deep hum"
operation.  The degaussing field of the HP monitor is strong enough to
cause some pretty major distortion of a monitor sitting next to it (just
try pressing the "degauss" button without cycling power :-).

The server starts up with a keymap that seems to assume an ISO terminal
layout.  This is silly, IMO, as long as the extended characters aren't
engraved on the keys.

	xmodmap -e "clear mod1" -e "add mod1 = Meta_L Meta_R"

will fix it.

What are the audio capabilities of the new boxes ?  The glossies I have
for the 715 and 725 state that they have audio I/O ports.  The one for
the 735 says CD-quality audio is optional while the 755 is listed as
having CD-quality audio.

I assume this means the 715 and 725 have integrated 8 bit audio (like
the 710) while the 735 has optional 16 bit and the 755 has 16 bit built
in.

Considering the Indigos and SS10's have integrated 16 bit this seems
strange on HP's part.

Anybody else know more on this ?

Hi...

I have experienced a regular occurence of my 400 now running under HP-UX 8.0
and VUE spontaneously giving me the boot in the middle of what I'm doing.

There seems to be a connection between my use of the mouse and this happening.
When I push the mouse button to select a window (or whatever) it just stops.
The station then won't respond to any type of input for 1 minute or so, and
then it logs me out and I get the login prompt.  I re-login and everything
seems normal again.

Can anybody give me a place to look for the cause of such a thing?

This is a 400 with 24 Meg and a swap disk.  It's served by a 370.

I am NOT a sys admin.  Our guys are really busy and have asked me to see what I
can find out about it, so feel free to get as technical as you are able.

I'd appreciate e-mail since we are also having all sorts of nasty problems with
our news feed.

Hi all,

I heard bout a Kit to get my HP DJ 500 upgraded to a 500C.
Where can I get the color extension, how much does it cost an is it worth
it?
Here in Germany the Kit seems to be unavailable... thanx HP ???

Hope to get an answer,

Martin

Not that I know of.  Though CREATEPROCESS does have an option that allows
you to start it up with NMDEBUG.  Or if you have PM you can set a break
point in another process at anytime.

I have an HP 42S, and I have read the manual thouroughly
several times.  But I'll be damned if I can figure this
out:

The calculator handles complex numbers just fine, but when
I use the built-in solver on a function with roots in the
complex plain, Ohhhhhhh nooo.  The calculator WON'T do it.
It tells me: "EXTREMUM".

So, is there a trick, or is this just one of the, albeit few,
lame aspects of the machine?

Thanks,

  Scotty AJ
