Hi everybody,

The following is a summary on using SUNCD Player to upgrade NeXT with
NS3.0.

Thanks a lot for those who replied to me. I just can't personally
thanks everyone of them.

I hope this summary would help the others.

Andy

  I upgraded a Turbo NeXTStation using a SUN CD rom drive a short while ago.
I had some problems getting the NeXT to recognize the drive correctly while
still in 2.1, but after a few reboots (make sure the drive is powered on
before booting the system) it worked okay.  I've had no problems with it while
running the 3.0 OS.
  Good luck!

  Regards,
  Matthew Plec

	We hooked up our Sun cdrom without any modifications at all.
In fact, since the upgrade, we have left the Sun CDROM drive on the
NeXT.  So far no problems at all.  You will recieve a message during 
bootup that states "MESSAGE REFUSED RECEIVED" or something similar

Have fun!

I used a Sun CD-ROM drive for my 3.0 installation. I  just hooked it to the  
SCSI port w/ the sun cable, rebooted, and it worked. Nothing special was  
needed.

  NeXT mail welcome !

We have been using a Sun CD-ROM to do upgrades for our own (26) systems and those of  
our NeXT community. It works fine. We are also selling (available now) a Toshiba  
CD-ROM (in a black enclosure for esthetics) as well. Everything works fine.

There's a problem here, I guess.  A 68030 NeXT has a Macintosh 25-pin
SCSI connector.  The Sun CD player has a 50-pin micro-SCSI connector.

So you need some piece of intermediate equipment that can be used
as a connector converter.  Like an external disk drive for the NeXT.

030 NeXT  ->  External disk  ->  Sun CD reader  ->   bus terminator
    db25      telco       telco  micro      micro     micro
                50         50    SCSI 50    SCSI 50   SCSI 50

Things drawn as -> are supposed to be cables, with the designated
connectors on them.  Connectors labeled "telco" are also known as
"centronics type" although their real name is "micro-ribbon".  Connectors
labeled "microSCSI" are also known as "SCSI 2".

The Sun CD reader should have come with a microSCSI terminator as a
standard part of it.

I don't know where you can get db25 to microSCSI cables, but that would
be another approach.  I don't have this problem exactly because I am
using a 68040 NeXT which starts out with a microSCSI connector.

Andy,

You'll need a special SCSI1 to SCSI2 cable, since you have a SCSI1 type interface  
on your 030 while the Sun CDROM player has a SCSI2 connector.  Other than the  
connectors there's nothing special about the cable.  These kind of things are  
pretty standard stuff.  You can get these from Next connection.

Your welcome anyway!  I hope that the above answers your questions.

Take care,
Tim

We used the cable which came with the Sun CD-ROM player, which to my untrained  
eye is a regular SCSI cable.

We were unable to install NS3.0 from a Sun CD-ROM player <<connected to a Sun  
that was accessible through NFS>>, but we were successful when we physically  
moved the same Sun CD-ROM player and connected it directly to the NeXT.

*************************
You need either a floppy drive or the ability to read at least one
magic file off the CD-rom.  Sort of a chicken-and-egg problem.  If you
can boot from a floppy, everything is ok.  Otherwise, you can make a
dummy boot disk (OD is ok) that will boot directly from the CD.  But
the file to make the boot disk is on the CD, and you can't read it
until you can run a couple of the programs from the floppy which allow
you to read the CD from a non-turbo NeXT.

If you can't get help more locally, write back and I will see what
I can do to help.

*************************
Works much faster than the Next CD ROM player.  The next CD ROM  
player features extremely slow access time.  You may save >20 minutes  
on your install/upgrade with the Sun hardware.  I've installed NS 3.0  
with SUN players on all types of Next hardware successfully.
