: Progress update. I got GS/OS to recognize the NEC drive at
: least, using your suggestions.  Here's how it looks now:
:
: IIgs -> Zip (Termination on) -> NEC (Termination off)
: Zip SCSI ID is 6, NEC is 5.
:
: The twist:
:
: If the CD caddy is already in the drive when I boot up, I get:
: "GS/OS can't read this disk (in device .NEC.CDROM.01.00)
: Do you want to initialize it?"

It seems that some CD drives have a built-in boot
track that can be recognized by firmware and some
do not. Apparently yours is one that does not. So,
put a disk in before you boot. 8)

: If I load the caddy after it's up and running,
: I get no indication from GS/OS, a flashing "BUSY"
: icon on the NEC LCD and the unit becomes unresponsive
: to the buttons on the face of the unit.  It won't even
: eject until I power the GS off.

See above.

: When trying to access CD from the Media Controller,
: with HS.SCSI2 set to Channel 1, I get "Error reported:
: $FFFF.  No message available for this error."  If I select
: AppleCDSC, I get "Error Reported: $002F. Device offline."
: These behaviors happened with several standard Mac-format
: CD-ROMs (are these formatted HFS?), and an audio CD
: (just want to hear Tom Waits from my IIgs - just once...).

I don't have a listing for the $FFFF code handy, but the
$2F means either "Drive is Offline" or "No Disk In Drive"
It could be that there is no driver installed to recognize
an audio CD. Come to think of it, that is one thing I had
not tried to do. I'm going to be installing a SCSI card
in the next couple days, then I may have answers for you.
I also need to get my GS/OS reference out in case I have
the same problems. The good thing here is that $2F is not
a fatal error, simply something can't find something else.
I would remove all drivers related to CD and reinstall
only one set and keep trying that until you find the
right ones. You quite possibly have a conflict between
the AppleCDSC driver and the HS.SCSI2. Question: Is that
NEC drive a SCSI2? If not, you may want to remove that
driver.

: The Media Ctrl CP lists the following drivers: AppleCDSC,
HS.SCSI2,
: Pioneer 2000, Pioneer 4200.  Ports: .NEC.CDROM.01.00, GAME
PORT,
: MODEM, PRINTER.

There are definitely too many drivers installed here.

: The driver(s) I installed for this CD-ROM came from the
: SiriusRam/NEC.CD.Driver folder, which contained NEC.Driver and
: CDRemote, an apparently non-functional NDA.

Those drivers should run your CD drive, but the Apple CDSC
driver is not needed with those, I think. As far as NDAs go,
every one that I use was simply copied to the Desk Accessory
folder and reboot. They all worked.

: Currently, these SCSI files are present in the System/Drivers
: folder: SCSI.Manager, SCSI.CD.Driver, SCSI.HD.Driver.  These
: are in the System/Drivers/Media.Control folder: AppleCDSC,
: HS.SCSI2, Media.Setup, Pioneer2000, Pioneer4200.

Again, could be drivers you don't need in there.

: All of which leads me to believe that either I need the
: Tulin drivers, or the NEC driver is installed incorrectly.
: An email to Wing Cheung about the Tulin stuff went unanswered
: anyone know where I can buy a copy of these?

Quite a few of the original developers of Apple IIgs software
are not working with them anymore, nor do they become involved.
I believe there was mention that Syndicomm was selling those
drivers now. If you can't find them I will and post the link
here.

: As far as the memory tests, I have run BitBanger, MemoryTest.CL
: and CVTech.MemTest - all have come back error-free, and I still
: get the odd boot behavior.  Same thing with the top off to
check
: whether the Sirius card pushing against the case was causing
: problems.

BitBanger is very good and thorough, so I think if that
says it's good, then it's good. That is all I use. Even
though other programs are provided with RAM-GS. I still
use BitBanger and have had no problems with it.

: A new problem has cropped up as well (or at least, I didn't
: recognize it before) - I can't get NDAs to install.  They
: seem to copy properly, but never show in the NDA list. There
: is a shareware program on my FocusDrive (forget the name of it)
: that is supposed to install NDAs and CDEVs. If I use that,
: they show up in the list, but they don't run.
: And, after selecting any of these newly-installed NDAs,
: GS/OS stops refreshing/redrawing desktop items (icons, open
: windows, etc.) until I reboot.

Again, I have never had to install an NDA or CDEV, simply copy
them to the proper folder, or the system folder and it asks if
you want it in the correct folder, and reboot.

: Finally, I checked the SCSI card as you suggested, Bill.
: As I suspected, the diode mod has not been made.  Time to
: dust off the soldering iron, I suppose.  Just as well.
: My skills have become rather rusty over the years.

It's an easy mod, just make sure you solder it onto
the correct locations. I use "1N4148" with the black
line towards the connector. I can even take a pic of
the back of my HS SCSI card and email it to you for
a reference. 8)
