July 17, 2023 – TRSDOS v1.3 System File Disassembly Project is Complete.
The TRSDOS v1.3 system file disassembly is now posted here.
While I have learned a great deal over the project, and a lot more than I knew when I did the Model I ROM, Model III ROM, TRSDOS v2.3, or even the earlier Overlay of TRSDOS v1.3, I don’t think I am going to go back and redo those pages. If I ever spot an error, or something that can be clarified, I will update accordingly.
