The Programmer

The Programmer’s Guide to LDOS/TRSDOS Version 6 is my favorite TRS‑80 programming book, and in my opinion, the most useful. The chapters include:

  • an overview of the operating system
  • device input/output, with information about filters and drivers
  • disk drive input/output, with information about writing a disk driver
  • DOS directory structure
  • disk file access and control
  • interfacing with supervisory calls (SVCs), including detailed information about parameters
  • other useful miscellaneous tables and topics

In other words, The Programmer’s Guide provides complete overview of all the information necessary to write a proper Model 4 program.

You can download The Programmer’s Guide at Tim Mann’s Misosys Software and Documents Page in a variety of different formats.
