I'm a bit puzzled about how best to run the bus cable to keep it out of harm's way, e.g. getting it accidentally pinched or crimped while sliding the CPU cabinet in and out for service. cabinet, but from there...?? Anybody have a picture or remember how this was usually done around the slide rails etc. to avoid trouble? drives and the controller, but I haven't seen any recommendations for the cabling Unibus between cabinets anywhere yet. In the rack I have where this appears to have been done, DEC supplied flat tie-down clamps that were positioned in the middle. If you had say two of these flat cables for example, you'd run both through the flat clamp, and screw them down with the clamp cover. I recently sold the system, I did not take a lot of pictures of the clamps, but if I find anything I will post. Bill Degnan twitter: billdeg vintagecomputer.net
