ZX Next Clones

The core of the Spectrum Next hardware is licensed under the GPLv3 free software license which has enabled the production of several clones and ports.

ZX Next clones

Spectrum ZX Next clones use the same FPGA core as an official ZX Next thus you can run the official NextZXOS distro and use it to update your core.

N-Go - The N-Go is a full ZX Next clone complete with 2 Mega Drive style joystick ports, an expansion port and optional custom case.

Xberry Pi - an affordable Next clone with a PCB roughly the same dimensions as a Raspberry Pi 3.

ZX Next ports

The Spectrum Next core has been ported to several different FPGAs with varying degrees of completeness and compatibility, including:

ZX-DOS - FPGA-based hardware recreation of the ZX Spectrum, created by Antonio Villena.

ZX-DOS+ and gomaDOS+ - ZXDOS+ and gomaDOS+ are the continuation of ZX-Uno. They are the same machine in a different case.

ZX Spectrum Next for MiSTer Platform - an incomplete ZX Next core for MiSTer FPGA compatible systems].

ZXTRES - The ZXTRES, ZXTRES+ and ZXTRES++ are Next clones with several alternative cores.ZXTRES wiki.

ZX-UNO - A Next clone in a Raspberry Pi form factor with composite video output. Very old ZX Next core.

Karabas Go - A Spartan-6 based devboard with a fully working Spectrum Next core.

UnAmiga and Unamiga Reloaded have ZX Next cores.
