NewDos/80 is a third-party operating system that was made available for the Radio Shack TRS-80 line of microcomputers beginning in 1980. NewDos/80 was developed by Apparat, Inc. of Denver, Colorado.

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.[1] 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.[1]
