ZX Spectrum keyboard computer was launched in April 1982 in the United Kingdom, and 35 years later, a team of developers has now been working on ZX Spectrum Next somewhat resuscitating ZX Spectrum by emulating Z80 processor in a Xilinx FPGA, using an optional Raspberry Pi Zero board as an accelerator, and adding some modern features like HDMI output and WiFi.
- FPGA – Xilinx Spartan-6 FGPA emulating Z80 processor in 3.5Mhz and 7Mhz modes
- System Memory – 512KB RAM (expandable to 1.5MB internally and 2.5MB externally)
- Storage – SD Card slot, with DivMMC compatible protocol used in the original ZX Spectrum
- Hardware sprites, 256 colours mode, Timex 8×1 mode etc.
- Output: RGB, VGA, HDMI
- Audio – 3x AY-3-8912 audio chips with stereo output + FM sound
- Networking – Optional WiFi module
- Joystick – DB9 compatible with Cursor, Kempston and Interface 2 protocols (selectable)
- PS/2 port – Mouse with Kempston mode emulation and an external keyboard
- Special – Multiface functionality for memory access, savegames, cheats etc.
- Tape support – Mic and Ear ports for tape loading and saving
- Expansion – Original external bus expansion port and accelerator expansion port for Raspberry Pi Zero
- Misc – Real Time Clock (optional), internal speaker (optional)
- Power Supply – 9V
Spectrum Next board can also fit into the original case, if you find the new design too… well new.
The Raspberry Pi Zero is used to bring OpenGL support to the ZX Spectrum, as well as more memory and a faster processor, so beside running retro apps on the ZX Spectrum Next, you can also run apps that would not work before. The good news is that the board already works, and you can run program in normal or accelerated mode, Doom, Wolfenstein 3D and more. The source code for the FPGA’s Z80 core will be released to the community.
ZX Spectrum Next has launched on Kickstarter, and has been rather popular so far having raised over £412,111 out of its £250,000 goal. If you want to upgrade your old enclosure, you could pledge £99 ($128 US) for the board only, but if you want the full package with the new enclosure, you’ll have to pledge at least £175 ($226). It’s probably not coincidence that’s the same price as the original ZX Spectrum with 48KB RAM when it launched in April 1982. Delivery for the board only is schedule for August 2017, while you’re expected to wait until January 2018 for the full version. Shipping adds 10 quids to the United Kingdom, and 25 quids to the rest of the world.
The Register reports there is no relationship between RCL, the company behind the failed ZX Spectrum-branded Vega and Vega+ consoles, and the team working on ZX Spectrum Next.
