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?"

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.

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 off 
line."

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...).

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

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.

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.

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?

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.

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.

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.
