Here's another one for you guys to mull over while I am away for two weeks.
Aside from the hard drive (which when the cube attempts to boot from tells me "bad version" as well as some checksum error that's probably because NeXTStep is not on the drive, and I set this drive to ID 0), I can't get anything else on the scsi bus to properly work. I have one cd drive that will just reset itself whenever invoked (a yamaha cd burner), even if I specified a different address, another that will blink it's front light no matter what address I specify (IBM OEM) and another that won't do anything at all (Apple CD 300e Plus). I also tried to use the floptical drive from my Indigo and it refused to work on anything other than ID 0 (and I was jumpering it to different addresses) and my scsi zip drive won't respond.
I have tried different cables and both internal and external terminators and I still can't find the problem. I also tried different configurations and it was still happening. The cube is powering the trmpwr pin so there is no blown fuse as well. The only other thing I can think of that is acting up is the MO drive but I doubt that it is somehow affecting the operation of the scsi bus.
I'm sure you did these things, but I have found myself pulling my hair at 3AM trying to troubleshoot stuff like this, and so I offer:
- Remove everything from the external bus
- Set your internal drive as though it is the only SCSI device on Earth. Check the manual for your drive, and set the jumpers as conservatively as possible
- If no success here, try another drive - prepared in the same, conservative fashion.
- Assuming that works, add one device to the external bus with appropriate termination, and recommended ID settings (there's some information in the FAQ suggesting the friendliest IDs for CDROMs, etc.)

The first thing I did was pull everything but the seagate hard disk off the bus but because I have nothing on the drive I didn't see how that would help. I have tried three different drives and they all act up differently and for addressing, the internal hard drive is 0, the cd drive is 4 and the ZIP drive is 5 (it can only be set to either 5 or 6).
