I intend to purchase either an IPC or an IPX in the next few months,
maybe together with a desktop module, SPARCprinter, etc.

My question regards the power requirements of such a machine.
Although I live in the U.S right now, I will (hopefully) graduate at
some point and will relocate back to Europe (my signature will betray
me :-).

[As we all know] In the US the voltage is 110V at 60Hz; back home,
however, we use 220V at 50Hz.  What I would like to know is whether
this will be a problem with the equipment.  Will I have to (from worst
to most desirable):
- buy a huge/large power converter
- replace all the power supplies (box, monitor, desktop modules,
  printer, etc, ouch!!)
- just replace a fuse
- just flip a switch
- just get the right power cord

Also, are any parts of the equipment special in this respect (say the
monitor) ?

Anyone who knows about this (or has gone through the same procedure)
and can give some info, I will appreciate.

Please reply by e-mail as I do not read this newsgroup often.

Thank you all for your time and attention.

Hello, we consider buying Sun-SparcStations.
One offer we got was 3 SUN-IPX or for the same money 4 IPX-Clones from New-Logichas anyone experience with these clones; what about Hamilton, Hyundai??
Are they really compatible, have they the same quality?

Thanks for your  help (and please excuse these FAQs)

We've had the same problems - 3 out of 7 of our monitors have totally failed
within the frirst 6 months (luckily we're on Sun maintenance),
and when I came in this morning this very machine had the random horizontal lines
you describe. Bad quality control (cheap components?) on ELC monitors
in general, I guess. We've had no problems with SLCs.

I have a Trinitron Sun "rosebud" monitor on my IPC 4/40.  I've
noticed that it has the slight shakes on occasion.  I did
eventually track the problem down to wiring in the building.
Apparently the wiring, some of which is old knob-and-tube type,
makes a big AC field due to the physical separation of the
conductors.

I even tried running my monitor and computer from a UPS system
unplugged from any wall based power; still got the shakes.  The
only solution was to move the computer to a different location or
turn off everything in the adjoining room.  My mahcine is on a
wooden desk.  Using a steel topped desk seems to help avoid the
shakes.

There is the same configuration system in a new building, no
problems.  I took my system to the new building and could not get
the system to exhibit the shakes.  It is definitely something funny
about the wiring near my mahcine.  Unfortunately no post hoc power
conditioning seems useful.  Some sort of soft steel "mu metal" like
material near the monitor to help absorb ambient H field would
probably be the most helpful approach.

There were some bad CG3 frame buffer cards back in 1991; this
would not be the problem afflicting the SS2.  My CG3 was
manufactured in June of '92, so it should be OK.

I wonder which 3rd party (i.e. non Sun) CD-ROM drives are plug and play

like to avoid installing any special driveer software (if possible).

Note that these drives must cover all functionality of the original Sun
drive, i.e.  I must be able to boot from the disk, play audio CDs,
mount disks, etc.

Please email, I'll summarize.

8500's and DATs definitely display the problem. It is better to disable
sync SCSI on the tape drive than on your host, especially if you have disks
on the same SCSI bus. This can be done with 8500's (ask your vendor for a
new firmware tape with sync SCSI disabled); unfortunately I have yet to find
a DAT that can do it. Certainly HP and WangTek (dunno about WangDAT) can't.

TTI sends their 8500's with sync SCSI already off. We got a tape from CoComp 
to do it on the ones they sold us.

Sun has a "patch" which replaces esp.o, but we were told by Sun that all it
does is suppress the "esp0: target x now synchronous ..." message. It doesn't
prevent the renegotiation from happening as far as I know.

I don't know whether this has anything to do with the original poster's poor 
performance problem with an 8500 at a specific location on the bus.

I am in the process of researching for the best laser printer
for my money.  We have recently looked at SUNs latest printer
which uses the memory on the SUN.  Unfortunately, I don't have
the product list at hand, I have forgotten the item number and
name.  Our biggest problem is finding a printer that can sit
on the network and be accessed by a heterogenous environment.
The majority of the work will be done with a SUN but others
such as an SGI will also use the printer.  (We are planning
to use the SUN as the queue manager).  Our second problem
we are planning to use the printer to print images.  We are
currently working on a NASA project and alot of the work we
do involves images.  

If anyone in network land has a printer they are currently using
in this type of enviroment and really enjoy it, could you 
please send me information on the company, item name, any
capabilities, costs and phone number.  I would greatly 
appreciate the information.

                                     Thanks,

For screen lifetime:              one from 1) - 3), whatever you prefer.
For lifetime of the hole monitor: 1) (but ONLY for longer breaks,
                                       e.g.  some hours )

That all the same for Mono, Grayscale or Color Monitor.

Something we used to do in the old UNIX-PC days will probably work quite
well for the dead 3/50 fans.

Remove the fans from the case (it's not particularly hard) and take them
down to your local stereo repair shop.  Not the place that sends your
stereo somewhere else; a place that really repairs them on the spot.

They carry fans that have to run very very quietly.  They can call the
manufacturer of the Sun fan and find out how many CFM (cubic feet per
minute) the fan moves.  They can then sell you a fan of the same size
and shape that moves the same (or more) cfm.  The big difference will be
that the new fan runs off of the AC current rather than DC from the
Sun power supply.  Your choices are to either wire the new fan directly
to the ac lines by the power supply (not difficult) or plug it directly
into the wall.

The end result is a quieter and more reliable fan.

Sure, the people who sold you the second drive.  If they're the ones
who are charging you hundreds of dollars for a piece of plastic, you're
buying a disk drive from the wrong people; I would also venture to
guess that you paid too much for the drive.

Yes..I asked a Sun engineer about this and he'd seen it before...we removed

I'm not sure about this - I tried various SCSI targets on the drive,
without success.  Maybe it depends on the PROM revision or something.
The jumper is the definitive solution - although it's an awkward beast
to get to.

Hello,

I wish to provide audio feed back (beeps and clicks) in an application
I am writing via on the SPARC's speaker. Even something like this would
be OK:

/*----------------------------------------------------------------------

void make_sound( r )
int r;
{
   int soundfd, i;

   if( -1 == (soundfd = open("/dev/audio", O_WRONLY|O_NONBLOCK)) )
      return;
   for(i=0; i<r; i++)
      write( soundfd, click, sizeof(click));
   close( soundfd );
}

BUT, the application will hang if some other process is using /dev/audio.
I though the O_NONBLOCK would prevent this. 

Can anyone provide a simple solution. Or point out my error?

Thanks

 There seems to be some confusion here - 

 Generally speaking:
 SPARC - means the processor architecture
 Sun4  - means a system architecture based on SPARC processors.
	 There are many SPARC implementations and all of them are used 
	 on machines based on the Sun4 (atleast from Sun) system
	 architecture.
	 Sun4c, Sun4m and any Sun<x> are variations of the base Sun4
	 architecture. All of them differ only in system architecture and
	 thus how the kernel is built and run on these.

 From an application viewpoint - any SPARC binary will run on any Sun4<x>
 based kernel/system.
