TRS-DOS (which stood for the Tandy Radio Shack - Disk Operating System) was the operating system for the Tandy TRS-80 line of 8-bit Z-80 micro-computers that were sold through Radio Shack through the late 1970s and early 1980s. Their own manuals recommended that it be pronounced triss-doss but the common derisive term referred to the platform as trash-eighties and thus this software was sometimes called trash-dos by loyalists of other computing platforms.

  • TRS-DOS (which stood for the Tandy Radio Shack - Disk Operating System) was the operating system for the Tandy TRS-80 line of 8-bit Z-80 micro-computers that were sold through Radio Shack through the late 1970s and early 1980s. Their own manuals recommended that it be pronounced triss-doss but the common derisive term referred to the platform as trash-eighties and thus this software was sometimes called trash-dos by loyalists of other computing platforms. TRS-DOS should not be confused with Tandy DOS a version of MS-DOS licensed from Microsoft for Tandy's x86 line of PC's. TRS-DOS was primarily a way of extending the MBASIC with additional I/O (input/output) commands that worked with disk files rather than the cassette tapes that were used by most other TRS-80 systems. TRS-DOS supported up to four floppy (mini-diskette) drives which used 5 1/4" (five and one quarter inch) diskettes with a capacity of 160K each. The drives were numbered 0 through 3 and the system diskettes (which contained the TRS-DOS code and utilities) had to be in drive 0.
  • TRS-DOS (Tandy Radio Shack Disk Operating System) est le nom du système d'exploitation de la gamme des micro-ordinateurs TRS-80 basés sur le microprocesseur Zilog Z80 (fin des années 1970 / début des années 1980). Il permettait la gestion de 4 unités de disquettes 5 pouces 1/4, de capacité 160 Ko. La version pour le modèle II gérait des disquettes de 8 pouces.
