The Programmer’s Guide To LDOS/TRSDOS Version 6

The Programmer’s Guide 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.
