Don't tape over the ribbon connectors. The tape will likely as not leave a residue that is harder to clean off than the dust that might accumulate. Re the terminators the spec calls for termination at the ends of a chain with no cable taps with more than a couple inches of cable each. That said I have made some real kludges work. The main thing is find the longest cable run and make sure there is a termination at each end of that as close to the ends as practical. Side cables of up to a foot generally do not hurt. Terminations within a foot of the real end do not generally hurt if desperation hits. Experiment within these parameters and you should be able to make things work fine. (Sometimes this experimentation is needed because particular drives may not be supplying termination power and the cable used to convert 25 pin Apple-Psuedo-SCSI to real 50 pin SCSI may not have the termination power wire connected. One last thing – for the external 25-50 adapter get one that is either very short or that has 50 wires in the cable that narrow down to 25 at the 25 pin connector. A 3 or more foot long 25 pin cable is a sure path to problems. {@_@}
