New powerful ZX Spectrum +2/+2A replacement motherboard, that comes integrated with a lot of hardware add-ons. It is designed to fit into ZX Spectrum +2 and +2A models' case with their excellent keyboards. The eLeMeNt ZX is a combination of modern and fast FPGA with the real Z80 CPU to achieve the best compatibility with ZX Spectrum's software and hardware.

Main features of the LMN128 FPGA core:

• ZX Spectrum 48, ZX Spectrum 128, ZX Spectrum 128 +2A, Pentagon 128, Pentagon 512 and Pentagon 1024 v2.2 memory model
• CPU speed 3.5/7/14/20MHz
• digital video output to TV/monitor
• standard ZX Spectrum 128 graphics mode with two video rams, Timex Hi-Res and Hi-Color, ULAplus palette, GigaScreen - no flickering, Scan line effects and more
  
• Z80 DMA
• 2× TurboSound FM, SounDrive/Stereo Covox/Specdrum sound
• DivSD + esxDOS

HW specifications:

• board fits to case of ZX Spectrum +2/+2A
• real Z80 CPU up to 20MHz
• FPGA core can hold T80 CPU up to 56MHz
• digital video output to TV/monitor with audio
• +2 and +2A keyboard compatibility
• FPGA replaceable board: Alchitry Au FPGA Xilinx Spartan7 board with 256MBytes DDR3 RAM
• 2048KB SRAM (main memory)
• 512KB FLASH (BASIC ROMs, ESXDOS and tests) + FRAM 8KB (system info, bios config)
• standard ZX Spectrum expansion BUS

• you must install the eLeMeNt ZX to ZX Spectrum +2 or +2A case and use its keyboard (USB keyboard is not yet supported)
• use original or similar 9V power supply (approx. 1A, polarity does not matter)
  

eLeMeNt ZX board only (provide your own FPGA and Z80)

• add your own Alchitry Au Artix-7 FPGA Board
• add your own Z80 CPU (20 MHz)
• includes short internal USB-A to USB-C cable
• includes 16 GB micro SD card with core files
  
• install the eLeMeNt ZX to ZX Spectrum +2 or +2A case and use its keyboard (USB keyboard is not yet supported)
• use original or similar 9V power supply (polarity does not matter)
