Understanding how to use TRS-80 ROM routines was vital for programming on the Model I and III. Jack Decker’s TRS-80 ROM Routines Documented was based on his articles in The Alternate Source.

The book contains five chapters covering:

1. Input and Output
2. Arithmetic Routines
3. Strings and String-Handling Routines
4. Miscellaneous ROM Routines
5. Reserved RAM Locations

Additionally, eight appendices provide deeper details including ROM differences, relocatable programs, and BASIC tokens.

The book includes a preface by Dave McGlumphy and an afterword by Charley Butler. Its detailed and instructive commentary made this an essential resource, going beyond basic listings into comprehensive explanations.

Jack Decker provides education beyond simple comments, explaining background, usage tips, and pitfalls.
