The (un)support provided is that of a non-file-structured device. Some preliminary utilities are provided which may read DOS (or KLDCP or RXDP) and RT format floppys. http://pdp-10.trailing-edge.com/BB-F494Z-DD_1986/01/10,7/rx20.doc.html CHAPTER 1 FLOPPY DISKETTES (RXA:) Diskettes are block-addressable devices, each of which contains 77 tracks of 26 sectors each. No file structure is defined by the TOPS-10 monitor, although it is possible for a user-mode program to define a file structure. http://pdp-10.trailing-edge.com/BB-F494Z-DD_1986/01/10,7/rx2ser.mac.html Title RX2SER -- RX20 Floppy Diskette Service for KS10s V006 Subttl Timothe Litt 11-NOV-85 http://pdp-10.trailing-edge.com/BB-F494Z-DD_1986/01/10,7/rtflx.hlp.html RTFLX is a utility that allows a DECsystem-10 to read and write files on RT-11 floppy disks and DECtapes. RTFLX can translate ASCII, PDP-11 binary, and DECsystem-10 binary files to and from RT-11 format. In addition, RTFLX can initialize RT-11 media, and can format floppys. RTFLX supports TD10 DECtapes, and RX20 floppy disks (2020 only).
