Z80 N.E. EMULATOR

This program is an emulator running on Windows systems for the Nuova Elettronica Z80 computer.

The emulator has been written completely from scratch (including CPU emulation) in Visual Basic 6, and it has the following features:

Emulation of the following cards:

• CPU card - LX.382
• cycle exact CPU emulation
• CPU clock frequency selection from 500 KHz to 50 MHz (beyond 15 MHz an extremely powerful PC is needed, which does not yet exist today)
• ability to select different default eproms to boot
• ability to select a custom eprom to boot
• continuous or step-by-step/step-by-step with jumping subroutines execution
• ability to set a breakpoint
• ability to directly change CPU registers and ram
• ability to load and run any binary file
• disk dump and restore of the complete emulator status


• hexadecimal keyboard and display interface - LX.383
• hexadecimal keyboard and display - LX.384
• tape interface - LX.385
• support for .wav files at any sampling frequency (.wav files on this site are direcly usable)
• support for two tape recorders
• speed 300/600/1200 bps
• FAST speed mode
• autodetect of reading speed
• .wav files written at 44100 Hz 16 bit


• 64K addressable ram
• ability to set protected ram locations (i.e. locations used by eprom and not writable)


• printer interface - LX.389
• video interface - LX.388
• complete support of text and semi-graphic 6 modes


• video graphic and printer interface - LX.529
• complete support of all text and graphics modes


• daughter board with beeper - LX.530
• alphanumeric keyboard - LX.387 (and LX.387-B)
• NOTE: to emulate BREAK keys of the original keyboard use CTRL+SHIFT key combination


• numeric keyboard - LX.549
• floppy disk interface - LX.390
• support four virtual disk drives on image files
• support of .IMD and DMK floppy images (images on this site are directly usable without any conversion)


• printer
• ability to print to video, print to file, or direct print to phisical printer connected to PC
• on-screen emulation of continuous forms or A4 paper


• interrupt card - LX.547

• ram editor
• input/output editor
• integrated disassembler
• automatic online updates check
• storage of various settings with automatic restoration at the next execution

The emulator architecture is multi-process, so a different .exe is run for each emulated interface. Communication between processes occurs via shared memory maps and inter-process Windows events.

Actually it has been tested on Windows 10 and Windows 11 only.

The emulator, although almost complete, is currently in BETA version and still under development. Any feedback is extremely welcome and can be sent by writing to info@z80ne.com
