So this is what I have done. Prepare for the cheeziest solution yet:
The UW disk is the only one on the 68pin connector of the BT-958. From
the internal 50pin connector, I have my internal CDROM, two of the three
narrow disks, then a 50-pin male ribbon cable connector to an external
HD50 female connector. On the *outside* of the case, I have the third
narrow disk drive followed by my ZIP drive. Today, my internal CDROM
is broken and in the midst of RMA hell, so I have an external CDROM hooked
up to the external chain as well.
But I have this super-long chain which may very well cause problems I
am not aware of yet. (Most of the important stuff is on the UW disk
anyway.) But I was consdering this thread, and I thought I could probably
move the external narrow disk interal, and put my ZIP drive on its own
controller, and shorten my SCSI chain. Does this sound like a better
idea?
Definitely. There's nothing wrong with taking the internal 50pin connector to
external devices, but if you are exceeding the 3m/1.5m Ultra cable lengths, you
will very likely have problems. Worse still, that damn pseudo-SCSI 25pin ZIP
connector is unlikely to be reliable in combination with any high performance
SCSI devices. This configuration is just waiting to have problems...
