My questions are: - How hard would these be to port to the VAX SIMH emulation? - Do modern VMS (e.g > 7.0) OSes support DECtapes? I figure it would be a nice way to transfer files between a PDP-11 and VAX system for example.. VMS have never supported DECtape, as far as I know... 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. And don't forget floppies...
