M3ZVM is a Z-machine interpreter for the TRS-80 Model 3 with 48K. Tested on multiple DOS versions. It was written by Shawn Sijnstra, ported from M4ZVM.

M3ZVM supports Z-machine versions 1, 2, 3, 4, 5, 6*, 7, and 8 within memory limitations. z6 support is minimal, and approximates the text only screen into the standard model.

Licensed under GPL version 2.
