VMS have never supported DECtape, as far as I know... Oh, bummer, always wanted to play around with DECtape :) The easiest way to transfer files between a PDP-11 and VAX would of course be DECnet, but in case you wanted to do it on a physical storage medium, the popular choices were RL02 or 9-track tape. But potentially, RK06, RK07, RM02, RM03, RM05, RP04, RP05, RP06 and RA60 were also pretty usable. Let's say I run RSX-11 on the PDP-11, what file system (I believe the PDP supports some level of Files-11) should I INIT the disks to? Can I INIT the disk on the RSX side and write to it on the VMS box? As for DECNET: Yes, that's obviously the sane way to do it. This is more of a "do it for the sake of doing it" type of an idea.. And don't forget floppies... True. Are there any 8" floppy emulators available on SIMH? :) I don't want to use anything boring..
