The operating system had additional commands and features that were not available in TRS-DOS, the native operating system for TRS-80 computers. NewDos/80 allowed TRS-80 computers to take advantage of advances in floppy disk storage that went beyond the initial 87.5KB 35-track, single-density, single-sided format. The system also corrected issues that early versions of TRS-DOS had with arbitrarily losing data due to errors in how it communicated with the contemporary TRS-80 disk drives' 1771 disk controller.
NewDos/80 had many options for specifying specific low-level disk configurations. Settings such as diskette formats, disk drive types, track geometry and controllers could be configured using the PDRIVE command.
Some typical NewDos/80 commands:
|Command||MS-DOS, OS/2, Windows||UNIX, Unix-like|
|APPEND||type file1 >> file2||cat file >> file2|
|AUTO||AUTOEXEC.BAT||~/.profile or ~/.login or /etc/rc*|
|CLOCK||prompt $t *||in some shells: PS1="...\t..." *|
|type file > prn||lpr|
|RENAME||ren or rename||mv|
