I snagged a Sun model 411 external SCSI CD-ROM drive fairly cheaply off of
eBay recently...since the seller was just across town, I drove over and
picked it up this evening.  When I plugged it into my IIGS and tried reading
CDs with it, though, it caused the computer to lock up.  If a CD was in the
drive at boot time, it wouldn't even finish booting.

The box has a Sony CDU-8012 mechanism inside.  I made sure there weren't any
ID conflicts with other devices on the bus, but it still wouldn't work.
When I swapped a Panasonic CR-523 into the case, it worked fine...a pressed
CD-ROM (a NetWare 5 CD) and a CD-R (an SVCD I burned last week) showed up
fine in the Finder.  I even opened some of the text files on the NetWare CD.

Is there something odd about the Sony mechanism that Sun used?  I figured a
SCSI CD-ROM drive is a SCSI CD-ROM drive.  One page I ran across through
Google indicates that Apple used the same mechanism in some of its
products...might there be some difference in firmware between the drives
used by the two companies such that the drive I bought won't work?

If it matters, the other devices on the bus are a Seagate ST34520WC
(Barracudas are dirt cheap nowadays :-) ) and a Wangtek 5525ES.  Both are
connected to an Apple High-Speed SCSI Card.

(It only cost me $8, and I was kinda thinking of swapping the mechanism
anyway since the Sony is one of those ghey caddy-loading drives.  The
Panasonic that replaced it is a more normal tray-loading drive.  Maybe I can
put the mechanism back on eBay, where a Sun owner might be able to use it.)

On another note, has anyone ever put System 6.0.1 on a CD-ROM?  It'd beat
doing the floppy shuffle when adding/removing system components or doing a
clean install.  I have software (for Linux and Win32) that'll produce HFS
and hybrid CD-ROMs, and I've copied all of the floppies onto the hard drive.
Is it a simple matter of dragging the contents of all of the disks into the
same folder, or is there more to it than that?

I've made a System 6.0.1 installer CD. Having all the files in one
folder won't do as the installer looks for specific disks with specific
names. What I did was make up a partitioned CD. I did this by taking a
small hard drive and partitioned it into ProDOS partitions. I
transferred the contents of each floppy into a partition and renamed
that partition to whatever that floppies was. Then I did a blind SCSI
copy(device copy) with Toast. The hard drive wasn't mounted at the time
and didn't contain Mac drivers. When done I had a bootable 6.0.1
installer CD.

Scott, what software do you use for this?

I found that out the hard way. :-)

Interesting...I was thinking of making a CD with a bunch of >=800K HFS
partitions (since mkisofs doesn't support ProDOS and the IIGS supports
neither Rock Ridge nor Joliet extensions to ISO-9660), but that approach
would necessitate use of a boot floppy.  That your CD is bootable
(presumably not El Torito, but something else) is even more interesting.

mkisofs (part of cdrecord) does this.  For Win32, it builds under Cygwin
(and maybe under mingw32, but I've never tried that).  It also builds under
Linux and most other UN*Xish systems (probably under MacOS X as well).

(cdrecord would be an interesting porting project for GNO...while I doubt
that you could burn a CD on a IIGS, you could at least build an ISO that you
could zap across the network to another machine with a burner.  You'd have
to create the image to an HFS or AppleShare filesystem, unless your image is
<=16MB.)

Well, since you didn't mention it I'll ask the obvious.  Is the SCSI bus
properly terminated?

Charlie

ISO?  Please?  Pretty please with et cetera on top?

Yes...with an active terminator.

I didn't write that...but check out my recent post to comp.binaries.apple2
of a utility you could use to create your own System 6.0.1 ISO (or ISOs of
other Apple II files).  I'd put up the System 6.0.1 ISO I made with it, but
the boot-disk image is missing the SCSI drivers needed for it to see all of
the partitions.  (There's also no telling how pissed Apple would get, even
though the only-readable-on-a-Mac Disk Copy images are free downloads from
their server.)

Sun's older machines used CD-ROM drives with a different default block
size (2048 vs. 512 if memory serves).  The difference appeared to be a
way to encourage you to buy their overpriced CD-ROM drives.

It's been too long since I last dealt with this stuff to remember anything
further about it.  Look for FAQs or Smart People(tm) who are wise in the
ways of Sun hardware.

As far as CD-ROM filesystem formats go, don't forget that you can put
ISO-9660, HFS, Joliet, and Rock Ridge formats all on one disc.  So you
can please the "we want ISO-9660" crowd while keeping the HFS people happy.

I thought it might be something like that.  If there's no way to make it
behave like a normal CD-ROM drive, I'll go ahead and put the mechanism up on
eBay.  I have a wide variety of machines at home, from a VIC-20 to a dual
Athlon MP 2100...but there aren't any Suns among them.

Been there, done that.  While mkisofs will write a partition table to the
CD, it doesn't appear to be able to create multiple partitions.  It
definitely doesn't know anything about ProDOS.  I've gone ahead and created
a utility that creates a partition table to string multiple ProDOS
filesystems together into one burnable ISO.  With a minor tweak, it'd also
allow the inclusion of HFS filesystems.

I posted the utility last night to comp.binaries.apple2, but the Spanish
spammers crapflooded the group last night and caused the post to expire
before it could leave the Cox news server.  Maybe it's just as well, since I
forgot to include the makefile in the tarball I posted.  I reposted (through
Newshosting) a fixed version this morning.

An ISO 9660 installer CD could easily be made but it wouldn't be
bootable. You'd have to boot off a System disk that has that FST on it.

Wayne

I'm not familiar with the program but maybe it doesn't need to
understand ProDOS or create multiple partitions. After making up
the partitioned ProDOS hard drive I attached it to a Mac and started
the Mac. Once the Mac had booted I turned on the hard drive. I then
started Toast and chose Device copy. It gave me a list of hard drives
including the one that wasn't mounted. The computer just did a block
copy and didn't know what was on the hard drive.

He might've meant "ISO" in the "CD image" sense, not "ISO-9660" sense.  I
just fixed a bug in my partition-table creator and added HFS-partition
support.  Between my IIGS, Mac, and Linux server (all networked), I made a
high-density boot floppy with Finder, Teach, ADU, the HFS FST patcher, and
SCSI disk and CD-ROM support.  By making that the first partition in the CD
image, I now have a bootable CD that shows all seven of the System 6.0.1
disks when it's inserted (only System.Disk has been changed, the others are
as they were downloaded from Apple).

If anyone's interested, the CD image (less than 3 MB) is available here:

http://alfter.us/files/sys601.zip

Extract sys601.iso from it and burn with your favorite app (Nero works
well).

The updated partition-table generator will be posted to comp.binaries.apple2
momentarily.

Yes, that's exactly what I meant.  Thank you!
