The LS-DOS 6.3.1 source tree is available on LS-DOS 6 format or MS-DOS format floppy diskettes, including all tools and TRSDOS 6/LS-DOS 6 utilities needed to assemble the entire operating system. This can be obtained from M. A. D. Software

Overview

This page lists a collection of programs developed by Logical Systems for the TRSDOS 6 or LS-DOS 6 platform that were not included in the LS-DOS 6.3.x releases. This includes important items like the Radio Shack hard disk drivers, as well as some utilities that probably didn't get included for good reason.

Since these programs were not part of LS-DOS 6.3.1, there was no way to determine if they assembled correctly and are infact properly working programs. They do assemble without warnings or errors.

LS-DOS 6.3.1 CMDFILE6 (/CMD)

CMDFILE6 allows Model I and Model III tape-based programs to be converted to diskette, and in some cases, for the base address of the program to be relocated to higher memory locations, an important issue when trying to run certain Model I programs on a Model III, as the Model III user RAM area started at a higher memory location.

CMDFILE6 was not an official part of TRSDOS6 or LS-DOS 6.3 and was never included on any Tandy, LSI or Misosys releases. Since CMDFILE6 was part of the source tree provided by Logical Systems, it is included here.

The source code for CMDFILE6/CMD was not published in "The Source" for TRSDOS 6.2.0.

LS-DOS 6.3.1 DW (/FLT)

DW is a printer filter written for the Radio Shack Daisywheel II printer. It was shipped only with the international versions of TRSDOS 6. This was one of the pieces of software Tandy forced LSI to write for free in 1983 when the Tandy-LSI relationship really came apart, claiming it was a necessary part of the international releases and thus was part of the contract to release a version for a German and French keyboard and video system.

The source code for DW/FLT was not published in "The Source" for TRSDOS 6.2.0.

LS-DOS 6.3.1 TRSFORM6 (/CMD)

TRSFORM6/CMD is the hard disk formatter, created for use with the Radio Shack hard disk systems which were based on the Western Digital 1000 (or its emulation), or the 1010 hard disk controllers.

The source code for TRSFORM6/CMD was not published in "The Source" for TRSDOS 6.2.0 and the executable was not included in any 6.3. release. However, it is an important piece of the Model 4/4D/4P platform, so it is included here.

LS-DOS 6.3.1 TRSHD6 (/DCT)

TRSHD6/DCT is the hard disk driver for the Radio Shack hard disk systems. which were based on the Western Digital 1000 (or its emulation), or the 1010 hard disk controllers.

The source code for TRSHD6/DCT was not published in "The Source" for TRSDOS 6.2.0 and the executable was not included in any 6.3. release. However, it is an important piece of the Model 4/4D/4P platform, so it is included here.

The source code to the LDOS 5 version of the Radio Shack hard disk driver, TRSHD5/DCT was also found in the Logical Systems source tree. It is included here for completeness, but is not part of the 6.3.1 release.
