     Hello everyone.  I need a little help with my 2/120.  My monitor died
recently, and I would like to connect a terminal up to the serial port to
use the computer.  Unfortunately, I can't figure out how to get this thing
into diagnostic mode.  I thought this was necessary to run off the serial
port.

     Thanks ahead of time for any help you can give me.

     Oh..  While I'm at it, does anyone have an old FE manual that has the
Sun-2 information in it?  Willing to give/trade/sell it?

     Thanks, again...

 Andrew> 	2D accelerated graphics
 Andrew> 	64M memory
 Andrew> 	800M internal disk drive total

We have both a pair of SS2s and an IPX, so I can supply some details
here.

The IPX has 2 SBus slots and a built-in cgsix (GX) 256-color accelerated
frame buffer.  This would normally take one of the three SBus slots in
an SS2, so there's parity there (unless you're going to run the SS2 as a
server, without a frame buffer).

Memory on both motherboards goes to 64M, as you said, though the IPX
uses 4Mx33 SIMMs, while the SS2 uses 4Mx9 SIMMs (but more of them).  The
4x9s are probably easier to find.  Mostly a wash here.

The IPX, until recently, only came with a 207M internal drive (and only
has one internal drive bay).  They now come with 424M internals, as do
the SS2s (but the SS2 has *two* internal drive bays, for up to 848M
internal).  Since buying drives from anyone but Sun is usually a better
deal, this is a wash.

The IPX comes with 16M RAM, while the SS2 (at least ours) comes with
32M.  Advantage SS2 by a few hundred dollars (about $500, I think).

The SS2 has 16 hardware contexts, while the IPX has 8.  This is the big
difference.  This means the SS2 won't start to degrade as quickly in
performance until more than 15 processes are active (the kernel eats a
context), but the IPX will start degrading after seven.  I notice this
most on my ELC (which also has 8 contexts).  This, again, makes more of
a difference in a multiuser context (server or similar).

The SS2 takes up a lot more of your desk.  The IPX can stand on its side.
The monitor is the biggest issue in either case, though.

The SS2 has "real" 25-pin serial ports, the IPX has 8-pin ports (but
comes with an adapter cable).

Megaherz ratings are becoming less reliable as more superscalar

Consider the MHz and the the Specmark numbers.  You're talking about
SPARC, a superscalar chip, versus the 486.  There are "envelopes" that
are now being pushed back (as in the past) regarding raw clock cycles
a chip can operate with.  Given that that envelope is feeling tighter
and tighter these days (until a revolution in chip _material_
technology comes about), superscalar design is where chip designers
and manufacturers will find their performance leverage.

Cycle for cycle, THAT will determine the performance leader of the next
few years.

The issue is not moot, regardless of whether you know of SSs with
expansion boards in them.  The various I/O interfaces, which are
usually located on the system board, still operate on the Sun SBus.
Similarly, many PC brands, Compaq (an excellent performer) being a
notable example, have video, serial, parallel and other interfaces on
the system board (on the EISA bus).  When you discuss expansion
boards, you are bringing in variables which may or may not have
anything to do with the merits of the bus.  For example, the Mylex
32-bit caching synchronous SCSI disk controller will probably
outperform any other controller (SCSI, ESDI, etc.)  you can plug into
that bus or come already installed on the system board.

Subject: Spark 670 config questions
Date: 6 Apr 92 18:06:02 GMT
Organization: University of Pennsylvania

We currently use a Vax 3000 to house a clinical and research medical database.
The database consists of about 1000 cases and we we have 20 files of data on
most subjects. We are also doing this with old Vax Datatrieve. We want to
move into this century and go to a relational system such as Ingres on a Sun.

A Sun salesperson quoted me a great price on a Spark 670 with two 1.3 gig
disks, 4 cpus, 64M memory, and some other neat goodies. We want to use this
system at the outset to allow about 10 to 20 people to log in simultaneously
and do a variety of tasks including WordPerfect, SAS statistical analyses, and
some data management. There will probably be no more than 3 or 4 people using
our database at any one time. The database grows by about 300 cases per year
which isn't much, but we do extensive database queries and pull the data over
to SAS for some very intense statistical analyses. After we acquire a new
system and convert to Ingres and SQL, we will also want to establish a client
server relationship with our lab's PCs both on campus via ethernet and via
telephone to PCs in researchers' homes. Here is my question. Does this
configuration seem seem sufficient for the needs I have outlined? Also, I am
looking to compare this system to a Vax 3000 and a Vax 8550 which we would
want this system to replace. How does this configuration compare to those VMS
systems? Can anyone out there in netland recommend a place, preferably anon
ftp where I can acquire objective reviews of Sun and other workstations and
bench mark results?  Thanks

I doubt if the 5GB is achieved by only changing for the long tape

And Wang dat also connects.
I heard both can be used for sun.

I have heard that some type of DAT can be an block device, which
can make filesystem usage, while another can only be a streamer.
I cannot tell which is which and what is what?
Please help!!

If you have to rely on fast ethernet performance to do fast calculations, you 
are doomed.  Also, a slow disk can be sped up by getting more ram.  Eight
megabytes costs about $300.   

Obviously a fast bus is good.  However a bus that is half as fast will do
fine for many applications.

We have over a hundred workstations and several servers.  We don't need to
load up our machines too much.  I can see that you do though.

I seem to have a problem with my Sparcstation.  After typing

The mouse continues to work perfectly and the swift application
of the Reset Input function in the Root menu resolves the

respite is just enough time to try to save any open files
before the system dies.

The system dies without any helpful message.  I'll be checking

You can get these informations from "The SPARC Architecture Manual" Version 8
Prentice Hall, ISBN 0-13-825001-4. I think, only a listing of the opcodes is 
not very useful, because you have to pay attention to some very "mysterious"

Don't forget the option of using a seperate box!!  We have a couple of the
Annex boxes (Xylogics makes them).  They hang on the ethernet, and have 
LOTS of smarts built in (too much so for some stuff!).  They provide you`
with 16 serial ports and a printer port (centronics) on some of them.  They`
download their software from a 'server' and can provide all sorts of modem
features etc.  I don't remember all the things they do since we just use
them for the basic serial ports.  It is nice being able to talk to a
serial port as a special device from any machine!! ie port 3 can be a port
on machine A while ports 1 and 4 can be ports from machine B.  They come
with the software.  Unfortunately, I can't remember just what we paid for
them - doesn't matter, since the paperwork to buy them costs more than 
the actual item!!  We make paperwork around here --- airplanes are a
byproduct (well it seems that way sometimes!)
