The application sounds fairly specialized and I'm not sure you will
find an SBus module that has the appropriate interface logic for this.
(Sun used to maintain a list of 3rd party SBus modules.....you might
try your local Sun Office).

--- OR ---

You might consider using a VMEbus module...there are a number available
with A/D and DI/DO functions. The SPARCstation could be linked with
an SBus to VMEbus adapter.  PTI builds such an adapter and VITA (VMEbus
International Trade Association) in Holland can help you with potential
VMEbus modules.

Just a thought......

6 months ago there were not `UNIX' modems out there that could take
advantage of a port speed of greater than 19200baud, and all the SBUS
cards that I see seem to be built to this expectation (or possibly
to 38400).

Is anyone aware of any SBUS cards that could actually drive a 
WorldBlazer at 115kbaud? or even 57kbaud?

This is a result of the host adapter driver (esp) negotiating for the sync.
offset and period with the device (i.e. the DEC drive). Usually this should
only happen once (during probe/attach). Sounds like you may be getting
some intermittent SCSIbus resets or some other data related error condition.

Well, the SCSA driver(s) are handling the conditions pretty well. What you
may want to check (to reduce or eliminate this) is your SCSI termination -
Only 2 - one on the SUN end (thats a given) and one on the last drive
on your SCSIbus. Also make sure TERMPWR is ok - pin 24 should be around 5V.
Last but not least, make sure your cables are as short as possible.

Hi,

     Can someone give me a hand?  I have a SPARC-1e and I can't get it to
boot up.  It checks out fine on all of the diagnostic checks.  I don't
have a console for it, I am running it from ttya.  My input and output
devices are set to ttya.  The problem I am having is that I have a 150M
SCSI tape drive connected to it.  I have SunOS 4.0.3 Sun4e and I have
SunOS 4.1.1 Sun4.  When I do b st()vmunix, here is what happens.  On the
4.0.3 tape, it goes to a prompt that says, "Boot:" I've tried inputting
everything imaginable here and nothing happens.  I can't CTR-C CTRL-D,
ESC, etc out of it.  I have to reboot.  When I try b st()vmunix with the
4.1.1 tapes, it says, "The file just loaded does not appear to be executable."
At any rate, it's very aggrivating having a really expensive Forth interpreter.
I have some possibilities as to what might be wrong with it but no real
way to figure out if that is the problem or not.  Here is a list of
what I thought would be the most likely things to be awry.

A) My SCSI doesn't have a termintor on the line.  I _think_ there _might_
   be a terminator built into the tape drive.  Would non-termination cause
   these errors?
B) I don't have my HD connect to my SCSI cable.  As yet, I don't have a way
   to do that.  It's a MAC drive and uses a SCSI that has the same Pin-Outs
   as my SCSI on my SPARC-1e in function but it is a totally different 
   kind of connector and I haven't built a conversion cable yet.
C) I built the SCSI going to my Tape Drive.  Could it be malfunctioning?
D) My tape drive is fried.  Unlikely because it seems to read properly and
   it does actually appear to run some sort of program from the 4.0.3 tape.
E) 4Meg of RAM just isn't enough to boot vmunix.  (very unlikely, though I
   have used VMS on a VAX before. :)
F) There are some more test programs that I should run on the Forth interpreter
   to try and find out more information but I don't have the programs.
G) **MOST LIKELY** I'm clueless and doing something stupid.

Okay, any last info I can think of...  It's running on the SPARC-1e Sparc-
Engine card with 2 serial, keyboard, ethernet, SCSI, 4M RAM, etc.
The tape drive has a little dubious setting thing on the back which is
set to 4.  The temperature and humidity in the room should be well
within tolerance.  I have a PDP-11 running nearby and I am assuming that
they are much more fickle...
     Anyways, any help would be really greatly appreciated.  Thanks in
advance.

The S-Bus card you are refering to is a "SCSI/Buffered Ethernet" or
SBE/S card (501-1869). It has a SCSI-2 interface and a buffered
ethernet - not a buffered SCSI.

Some more information to the problem.  The Sun IPX is running SunOS

Not entirely true.  You can connect two (2) (exactly 2) 10BaseT transceivers
with just a crossover cable.  This is not an accident; 10BaseT was designed
that way.  For three or more, however, you need a hub.

Keywords: modem serial RS-232
Organization: Northeastern Ohio Universities College of Medicine
Date: Sun, 16 Aug 1992 03:44:30 GMT

Without going into a mathematical discussion, Shannon's theorem
implies that the maximum information rate that one should expect
from an average voice grade telephone circuit is around 24,000 bits
per second.  The Telebit Worldblazer modem promises around 23,000
bits per second, half duplex.  These are uncompressed base rate
figures.  With factal algebra or something new, who knows what
we'll be able to achieve.  Even LZW compression can obtain up to
3:1 ratios on plain text, so you need more than 57.6Kbuad (a
standard interface rate) to get full use from the modem.  115Kbuad
is the next standard rate that is commonly used.

Driving the modem async is not terribly efficient at such high data
rates.  Of course, the Worldblazer also supports SDLC sync
connections.  Of course, also, sync connections are pretty alien to
the Unix world.

If one does the compression in the host, an interface good enough
to support the base rate will suffice.  Many modern modems,
however, offload the compression to a procesor in the modem
itself.

Making target 3 sd0 actually makes some sense to me in terms of
internal and external drives on Sun workstations.  Many of our external
drives are not easily jumpered to change the drive target number
and these are all set (with no jumpers) target 0.  By making making
the internal drive (most often the only drive) target 3 Sun has
allowd the internal drive to be sd0 (pleasing most people who would
think that if there is only one drive this is what it should be called)
AND they have made it possible to add an external drive without jumpering
or changing the target number from 0 and not conflict with the internal
drive(s).

What I don't understand is the LUN stuff.  Is this used anywhere
or is it just historical.  The sd numbers on a Sun4 (not 4c and I have
not yet seen the 4m) are really strange because of the provision
for LUNs.

Subject: Pinout P4 connector on 3/60 ???
Organization: PTT Research, Dr. Neher Laboratories

Does anyone know the pinout of the so-called P4 connector on the
mainboard of a 3/60 ? Normally it is used for the optional colour frame
buffer.  I have been told that it is just the buffered 68020 bus, but I
don't know where to find the pinout.  I might be able to find out by
running the CPU in tiny loops and probing the connector pins with an
oscilloscope, but that can easily take hours or even days.  So, any
information on this matter is appreciated.
