[Blind-sysadmins] old operating systems

Hi. I recently came across emulators for old hardware such as IBM 360/370/390, and digital equipment's PDP line. Does anyone on this list have any documentation laying around for this old hardware, and for the following operating systems? Any OS for IBM 360/370/390, especially VMS or TOS TOPS10 on the PDP 10 or any of the different operating systems that can run on the pdp 8, pdp11, PDP 15 or VAX? RFB&D used to have a lot of manuals on tape, but I guess it is all gone now. Many thanks Phil
