Not the OP but I have always been amazed by the quality and completeness of IBM’s documentation on their systems and peripheral devices. You can read it just for pleasure.
- pjmlp 6y agoWhich continues to this day, most critical information is found on Red Books collection.
- cptnapalm 6y agoAny idea how one would find hardware documentation? I have an old "small" mainframe and I'm curious about some of the hardware (backplanes, connector pin outs, etc) but after dozens of hours spent searching, I only found an SSA pinout by a curious hardware engineer.

- epc 6y agoAt some point in the past twenty years IBM downsized its technical writing teams. When I started as an intern in 1990 there were ~250 people in the “Information Development” group in Poughkeepsie responsible for MVS, RACF, RMF and a variety of other mainframe products (plus hardware documentation). Today, there’s now maybe 20–25 people left in Poughkeepsie covering twice the workload as other products consolidated there (Endicott closed, Kingston closed, etc).
