Summary: How do you fix a Sun 3/60?
Date: 23 Nov 92 17:02:09 GMT
Organization: /etc/organization


    I would like to be able to recycle the old Sun 3 computers that turn
up in electronic surplus stores but repair info from Sun is very hrd to
find. Would some experienced Sun repair person like to write an essay
on the subject?
    One typical case goes like this. A board for a Sun 3/60 part number
501-1334-25825 was found with its boot ROM missing. A ROM from
an older 3/60 was plugged in but it didn't work. All the leds lit up
and nothing happened. The ROM was numbered 520-1665-05. Will the ROM's
from different 3/60 boards work interchangebly? Or does each version
need its own ROM? What is the part number for the latest and least buggy
ROM?
    Are there some likely things that go wrong with 3/60 that are
easy to diagnose and repair?

First off, you DON'T need the format.dat entry for the drive.

I simply don't understand this fetish people have with format.dat entries.
Earlier this year many besides myself showed how easy it is to do it manually.

All you NEED to know is the total formatted-capacity data sectors.  For the
Quantum ProDrive 425S this number is 833,150.  One would then feed that
number into a program I wrote which will calculate the optimized parameters
that one should feed to format().  Since I have multiple 425S drives on my
Sun-3/60 (and other) systems, I'll save you the trouble.

Remember that with SCSI, the ONLY operative parameter is the sector(s).  The
concept of heads, cylinders, tracks per cylinder, etc. aren't pertinent to
drives with variable geometry (such as the 425S).

For the Quantum 425S, my program suggests:

	cylinders:	1754
	heads:		5
	sectors/track:	95

That will give you use of all 833150 formatted data sectors, and with the
default newfs and 10% "lossage", you'll have over 390MB available for files.
SunOS is better than HP-UX in this regards; I get only 385MB on my HP-9000/7xx
boxes with Quantum 425S drives.

What you need to do when format() asks you the stuff is:

	number of data cylinders: 1752
	number of alternate cylinders: 2
	number of heads: 5
	sectors/track: 95

Because of SunOS' requirement for the alternates, you lose 243KB with each
alternate cylinder.  Another choice for the 425S is:

	877 cylinders, 10 heads, 95 sec/trk, for 486KB per cylinder

Then go into the "partition" sub-system of format() and set it all up to
your preferences.  WHat I do for is:

	a: 0 1754/0/0
	c: 0 1754/0/0

Works fine; I've been using 425S drives on Sun-3/60 systems for over 20
months now with no problems.

So far I've heard everything from debate in this newsgroup to SunFlash
anouncements to citings in product announcements. When you work on our
kind of timelines (spend it now or lose it, not very unusual in Fortune
500 companies) you have to go by what the vendor says and whatever
catalogs they can provide you at that time. For the SPARC 10, we had
the May 1992 catalog which makes NO mention of 10 Base T but does make
an obscure one line reference to an AUI Adapter Cable that plugs into
the Audio port. The sales rep knew nothing of this at the time. 

|> On the whole, I approve.  10baseT is the modern wave.  If somebody has

As do I. A very good move on Sun's part. Once again, the whole point
to this story is, Sun could have done a better job of informing both
the customers and their sales reps--not leave it to newsgroups and
obscure references.

I have a Sparc1+ with two internal SCSI devices and a floppy in the
pizza box. I'm thinking about replacing the floppy with a 3.5" MO-disk,
which is a SCSI device as well, so I need a third internal SCSI adaptor.
What would you need for that? Could you just make a flat cable with
two plugs and attach two devices to it? Or are there electronics
(drivers, daisy chain) necessary?

Please excuse my naivity in hardware questions.

Well, the folks who advised me to check the partitioning were right.  
I had formatted the disk placing all the available space in the 'a' 
partition.  So, 

    newfs /dev/rsd0a
                   ^

got the job done.  Then, after 

    mkdir /files1

with the line 

    /dev/sd0a /files1 4.2 rw 1 3

added to /etc/fstab, 

    mount /files1

added 620 beautiful megabytes to my filesystem.  I dumped about 60 Mb of 
data to the new disk.  

Then things got wierd.  I shut the system down, and on reboot, the new 
disk would not mount.  Attempts to do so by hand produce the following 
result ...

    {vulcan:32} mount /files1
    mount: /dev/sd0a on /files1: No such device or address
    mount: giving up on:
       /files1

even though 

    {vulcan:33} ll /dev/sd0a
    brw-r-----  1 root     operator   7,   0 Nov 16  1988 /dev/sd0a
    {vulcan:34} ll -d /files1
    drwxrwsr-x  2 root     wheel         512 Apr 30  1989 /files1/

shows them both to be present.  Can anyone point me in the right 
direction ?!?  

Reformatting and making a new filesystem each time I reboot is NOT an 
attractive option !!!!  And that seems to be the only way this thing 
wants to work !!

I just installed a Micropolis 1558-15 ESDI hard drive into a Sun
shoebox and am trying to install SunOS.  My problem is with format.
I invoke format, specify drive and drive type, enter the defect
list (I think I'm doing this right) and then run format.  Here's
the info/error messages echoed to the screen:

  Verifying media... (etc)

Is this an operator, a software or a hardware error?  How do I
correct it?  The system is a Sun 3/60 and the OS version is
4.1.1.  I also tried 4.0.3 with the same results.  The drive is not
new and may have been used in a PC.  The system was working fine
with a Micropolis 1355 just before the switch.  The jumpers on the
1558 are for hard sectoring, drive select 1, spin-up with power on,
and 35 sectors, 512 bytes/sector(formatted) and 595 bytes/sector
(unformatted).

Thanks...Phil.

Organization: PANIX Public Access Unix, NYC

I remember some discussion of FPT when IBM first introduced it. I seem to
recall that there was mention of some potential problems with FPT too.

However... Assuming FPT is the solution we seek, where do we go about
terminating a Sparcstation 2? Obviously, the external end of the chain, but
what about inside the box? I have yet to get a straight answer as to where
(if anywhere) the internal part of the SCSI bus is terminated (I suspect that
it isn't but have no real basis on which to judge).

Presumably this will mostly be an issue with fast SCSI-2 cards, in which case
we'd terminate on the card first? Or would the card come preterminated on
its end of the chain?

How much would an FPT terminator cost?

Oh, while we're at it... I've got a long chain of SCSI devices working on a
Mac and I have no doubt it will fail miserably on the Sun when we try to move
it. This is all SCSI-1 stuff. Does FPT apply to SCSI-1 (I thought it did)?
does it also help cope with dicey cabling setups, as it does with SCSI-2?

Thanks...

We just moved the frame buffer cards from two Sun 4/110 that we were using

two frame buffers) and it seems to work. There are a few problems though.

With the second frame buffer installed the machine doesn't read the EEPROM

how many times have you had a ":"(*E^ AUI connector SLIP OFF?  Slide locks

Not necessarily.  Many companies that have a fixed price product
without discount structures for different customers (I can think
of plenty) will give their academic / education customers some
sort of discount (you can imagine the reasons).

I too would like to know of any problems with this - running under SunOS  
4.1 actually.  Sun Tech support gave me the impression that there may be a  
patch available for SunOS 4.1(.1) that will allow 2GB disks to work.  Does

I'm using an HP 1/2 inch 88780 tape drive on a Sun. The major problem 
i've seen so far is the inability to read a tape past a bad spot.

Some of the tapes i need to read are OLD and have bad spots on them. When
the drive sees those it fails after a number of retries. The next command
sent to the drive causes it to rewind the tape and start over again. This
makes it impossible for me to read past that bad spot.

My feeling is that this is due to the Sun SCSI device driver. Is there a 
solution to this problem?

Any suggestion would be very appreciated.

But then Lotus sells a lot more copies of 1-2-3 then Microsoft sells of Excell ;-)

Subject: convert b&w monitor to greyscale?

We have a spare GX card (aka cgsix) that we'd like to install in a
SPARCstation 1.  This SPARCstation 1 currently has the bwtwo video
interface.

My office-mate has an IPX with greyscale and it has a GX card in it,
so that's what they use for greyscale.

The connector on the back of the SPARCstation 1 monitor isn't the
right kind for greyscale; on my office-mate's monitor there are 3 coax
connectors as part of the video connector, in addition to the rest of
the pins.

It seems to me that converting a b&w monitor shouldn't be that hard;
they probably just short together the 3 rgb coax cables.  Does anybody
know if this can be done?  Does Sun offer an upgrade to greyscale for
b&w monitors?  Does any 3rd party hardware company?

Please respond with email and I'll post a summary.
