“The Spectrum Next is fully implemented with FPGA technology, ensuring it can be upgraded and enhanced while remaining truly compatible with the original hardware by using special memory chips and clever design,” said the organisation behind it, which includes Rick Dickinson who was part of the ZX80, Z81, ZX Spectrum, Plus and QL design teams, and Jim Bagley, who apparently holds a world record for squeezing Dragons Lair into a ZX81.

Unlike the original, it has an HDMI output alongside RGB, VGA and audio.

And if the Z80 is not providing enough through-put, a Raspberry Pi zero can be clipped inside to add more umph.

At a glance:

Z80 normal and turbo modes

512kbyte RAM up to 2.5Mbyte

SD Card slot with DivMMC-compatible protocol

DB9 compatible joystick port

PS/2 port for mouse with Kempston mode emulation or external keyboard

Mic and Ear ports for tape loading and saving

Proper keyboard

Original external bus expansion port and accelerator expansion port

Port for Wi-Fi module

Real-time clock

Optional Raspberry Pi Zero as a slave accelerator board (GPU + 1Ghz CPU + 512Mbyte RAM + USB + second monitor)

Anti-brick feature for bad updates

This is not the only attempt to bring back the Spectrum to the right is the ZX Spectrum Vega.
