The full settings are 9600, 7, E, 1.

BTW, the card is the one with a DB-9 connector and two little ribbon cables
connected to it.   Should be in slot 6.

| The DMA controller you have uses a 16 bit counter register. This limits
| one transfer to 64 KBytes (65536). It also is not capable of using a
| value of zero as meaning the full count. This leaves you at 65535
| at most. And that controller is word-oriented (I believe, it's been
| a long time). So you must round down to the next lower even count, 65534.

Yes, but that is no excuse for not accepting larger transfer sizes, and
simply reprogramming the DMA controller part way through the transfer
(as many times as needed), along with setting up the SCSI chip to
match.

That is what SGI does (different models have different limits on their
DMA hardware, from 64K to essentially unlimited, except by physical
memory).  On all of these we do DMA's up to 4 Mbytes to SCS devices by
default, and up to just about all of physical memory if you reconfigure
the kernel to allow it.  Yes, it is a bit more programming, but
that is no excuse for not doing it right.

Creating tapes (in particular) with a different block size than
requested is simply braindead.  Far better to simply disallow transfers
above 65534(or 5) bytes, than to break it up that way.  You can waste
tape that way also, as well as making it very difficult to read tapes
on other systems without such silly limitations.

But I'd rather not use up my last S-bus slot.  Most serial expansion

That's a good point, but not with respect to ISDN:  There are
some Meridian modems that work through our Northern Telecom
phone switch that can give you 56KB - 64KB if you're within
about a 5 mile (as the copper lays) distance from your phone
switching office.  If you don't need a generic modem for dialing
up lots of systems, it might be the best solution.

We have an older Ciprico TapeMaster controller from a Sun 2/120 which we
have put on the Sun VME-to-Multibus adapter for use in our Sun-3's.
We'd like to put the tape controller in a 3/110 rather than in our
3/160 server, so that we may (someday)  move the 3/160's noisy disks
out of the user terminal room while leaving the tape drive there.
We have set the jumpers on the adapter board according to Sun specs,
done a "/dev/MAKEDEV mt0" on the 3/110, and copied the tm0 and tm1
entries from the GENERIC kernel config file to the one for the 3/110
(a diskless machine).  However, no luck getting it going.  Ideas?

I tried this myself a couple years ago.  X term at home and SS2
at work, with a couple of really high-end telebit modems.  It
worked, but it was a pain, and slow.  I think that Illinois
has ISDN service available.  Call the phone company or your local

Recently I connected a Toshiba XM3201B CD-ROM drive to a SparcStation1+.  The
drive was originally for Macintosh.  Running a piece of code which 
modifies the expected block size of /dev/sr0 makes it work fine.

No booting from this CD-ROM drive, though.

If you already have a Toshiba CD-ROM drive, you can do it too.
If you don't, then buying one for Sun is the best way to go.  You can
boot from a Sun CD-ROM only from a CD-ROM drive for a Sun.

Check the June 1989 Sun Tech Bulletin issue. It contains a description
of the SCSI subsystem in use on Sun machines of architectures other
than `sun4c' (which use Sun's newer SCSA).

I did write some code for an "OLDSCSI" device driver some time ago, but no
byte of it has ever executed due to lack of a proper test setup. If you
want to have a go at it, send me mail and you can alpha test it for me :-)

The New Products section of the April UNIX World (Vol. IX, No. 4, April 1992) 
mentions an overhead projection system for SPARCstations called Proxima Ovation.
It's comprised of an SBus-base board connected to a flat panel display that sits
on top of an overhead projector. It doesn't say if it's colour. The company is called 
Sunburst Computers Inc., 187 Calle Magdalena, Ste 102, Encinatas, CA 92024; 
619-633-1680. They list the price for the Proxima Ovation at $9495.

A special "deal" in Sun-Air Force contract permits us to buy a 630MP
at a price that could be reasonably described as "dirt cheap." The
processor upgrade to a 4 CPU version is, however, at "list" which
was almost as much as what we would pay for the CPU. The process of
adding a second CPU card was described as being about as hard as adding
memory. I have been trying to locate 3rd party sources for the Cypress
SPARC MB cards that I understand that Sun uses or for their equivalent.
(I have not been able to get Cypress interested in giving a quote for
quantity = 1.) Any assistance is greatly appreciated.

I refused to pay Sun $40 for a cable so I ordered it from a place that
specializes in cables and such.  Rogers Specialist on +1 805 251 2520
(voice/fax) did it for $18 and shipped it UPS.

It's frustrating that Mac cables would work except that the

I want to expand my SUN-IPC from 24 megs to 36 by removing the 4 1x9 simms
and replace them with 4 4x9 simms.  My question is, can I use generic
4x9-70ns simms here or are there different types.  I have tried one set of
4x9-ns but the IPC tells me about parity errrors (could be the chips though).
Looking at the part numbers on the chips show:

   Good 1x9-80ns simms:    7 chips of TC511000AJ-80
                           1 chip of  THM91000AS-80
                           1 chip of  9027AAA

   Good 4x9-80ns simms:    7 chips of THM94000S-80
                           1 chip of  TC514100J-80
                           1 chip of  9048AAA

   Tried but failed 4x9-70: 9 chips of TC514100ASJ-70

Sounds like a simm is not just a simm (in the generic sense of 4x9-80) but
there are different types.

Any light on this would be greatly appreciated.

P.S.  Could someone explain the Coding on the chips translate to??

Thanks in advance,

Oh, but I think the point was that Sun/Viking/SVr4 was the combo
that would allow this Multiprocessing and that the Sun chips would
be *affordable* (much in the same fashion that 4 4MB Simms are

    Configuration Sun 4/65. 16 meg. SunOs 4.1.1b

    Scsi bus looks like this:

               Sparc 1+ ( 4/65 )

               Wren VII 1.2 gig drive.

               669 meg disk with 150 meg tape drive
 
               Storage Tek 3480 cartridge tape drive. 

     The local adminstrator has added up the scsi bus length adding internal
   and external bus lengths for a total of 4.4 meters. We thought sync
   scsi was a little more sensitive to length so we deleted the Wren VII.
   Errors dropped down but didn't disappear completely. Ideas greatly 
   appreciated.

	Is that the reason why I can't get a Sparcstation 19" mono
	monitor to work on a Sun 4/280?

		Thanks
