Vezza is a Z-machine interpreter for CP/M version 3 and above, requiring a z80 CPU minimum. Tested on multiple hardware versions. It was written by Shawn Sijnstra, ported from M3ZVM and M1ZVM.
Vezza supports Z-machine versions 1, 2, 3, 4, 5, 6*, 7, and 8 within memory limitations. z6 support is limited to non-graphics and has many workarounds to reduce to the standard screen model.
Core code licensed under GPL version 2.
