Help Setting Up SCSI Chain (HD & CD on an Apple IIgs)

[Tempest]

This is a bit of an odd problem for an Atari board, but I figured I'd post this here as well as the Apple II newsgroup just in case someone here has a clue as to what the problem could be.

 

I have a ROM 1 Apple IIgs with a Rev. C Apple SCSI card in slot 7

(system is set to slot scan on boot). I have a Microtech International

HD (SCSI ID = 3) and a Optical Access International CD drive (SCSI ID =

4) that I want to hook up to the IIgs. The setup was working when I

bought it, and came with a termniator that appears to be a pass-through

of some sort.

 

Currently I have the HD connected to the SCSI card via one port on the

HD and a terminator plugged into the unused port. This works just fine

and will boot from the HD if it is powered up when I turn on the IIgs.

The problem comes when I try to hook up the CD drive. No matter what

combination I try with the terminator placement the system fails to

recognize either drive. I've tried putting the terminator on the

unused port on the CD drive, putting it between the HD and the SCSI

cable going to the CD drive, and putting it between the SCSI cable and

the port on the CD drive (basically in all possible combinations). No

matter what I try the system just hangs at the boot screen when the CD

drive is hooked up.

 

Note: The SCSI numbers were set this way when I got the drives, but I

just looked up an FAQ which said that the boot drive should have the

highest number. However when I set the CD ID number to 2 and had the

HD set to 3, it still didn't work. I'm not sure if this is a red

herring or not, but I thought I should mention it.

 

Can anyone help? I'm completely stumped.

Try the link in my signature. Several folks hang out there who would know about the IIGS. I've never owned one, so I don't really know. I've never had that kind of SCSI problem with my old legacy Macs before.
