The VAX-11/730 System Installation Guide (EK-SI730-IN-003) has information about how to load the catch pan. Given all the 90 degree and 45 degree folds, it's the sort of thing you only want to do to a fresh cable once. There might also be a specific 11/730-Z detailed installation manual. I have a memory of one but don't know the part number. My memories of those days (we had two 11/730s) is that if you don't do it the way they did, either things won't reach (or be on the wrong side to fit into bulkhead connectors) or you'll have to redo it. https://archive.org/details/bitsavers_decvax730E83_4699164 > Exactly.

We did have that. It was nearly essential. We had the CPU, memory, and the default (as shipped) peripherals. Everything else went into our BA-11K FWIW, we only had the RB80/RL02 version. Tape was a TU80 with the controller in the BA-11K. Our COMBOARDs also went in the BA-11K, but that was also for our convenience of swapping out our own product for testing and firmware swaps, etc. -ethan
