LS-DOS 06.03.01 System Disk

LS-DOS 6.3.1 was recently made available on the Internet by Misosys, but if you can't download it yourself and get it onto a Model 4 diskette, you can order it right here. The original LS-DOS 6.3. upgrade documentation is included. (This is not the full system documentation, just the changes made since TRSDOS 6.2.)

To order single-sided version, specify 4GR6301S $6.00
To order double-sided version, specify 4GR6301D $6.00

The Source Code for LS-DOS 06.03.01 is also available. Click here for more information.

TRSDOS 01.03.02 System Disk

The last version of Model III TRSDOS 1.x widely distributed by Tandy. All Model 4/4D/4P systems came with this software. We will replace the MODELA/III file with the latest version unless you request otherwise.

To order original version, specify 4GR1302 $5.00
To order version with latest MODELA/III file, specify 4GR1302M $5.00

Applications and other items

For the following applications, replacement diskettes are available. If indicated, you must include a photocopy of the label on the original diskette as proof of ownership. Items that don't require proof of ownership are to the best of our knowledge now in the public domain or the copyright owner has granted the limited right to replace damaged diskettes. (Besides, what other computer and operating system could this software possibly ever run on?)

There is a charge of $5.00 for each diskette replaced, plus shipping.
