Eh? An RL is just a cartridge disk drive, not a format. It would depend on what the operating system you are using wanted to put on it.Similarly the RX is just a floppy drive. In my memory, there wasn’t much UNIX use of these drives. The main reason the driver existed on theVAX unices was to write the Console Floppy Disk in the 780 (which was in RT-11 format).What are you trying to do?On Jun 1, 2020, at 6:18 AM, Paul Riley <paul@rileyriot.com> wrote:Team Unix,Is there a Windows or Linux utility to create a disk image in any of the above formats, from a local folder tree?Paul
