Z-FIGHTER is a Z80 hobby computer loosely based on Grant Searle's CP/M on breadboard project. As a fully assembled unit in its custom 3D-printed enclosure, Z-FIGHTER has a handheld-style form factor with front panel accessories intended for user-created software and games. Connected via serial to a computer or terminal, Z-FIGHTER can be used to enjoy a full CP/M 2.2 environment or Microsoft BASIC in ROM. Finally, a parallel port and external CPU control pins are provided to the user for hardware hacking and expansion.
