are based on Programmable Logic Devices (PLD) – an electronic component used to build reconfigurable digital circuits. Buryak A ZX Spectrum compatible computer with a real Z80 cpu, VGA, Turbosound, PS/2 keyboard, Kempston joystick, customized for Raspberry Pi 3B case. Centoventotto A ZX Spectrum clone made by Mario Pratto in 2022. Chrome and Chrome 128 Chrome and Chrome 128 are Spectrum clones featuring a 7 MHz Zilog Z80 CPU, 160+64 RAM, PlusD floppy disk interface, AY sound chip, and an RGB SCART port. eLeMeNt ZX The eLeMeNt ZX was developed by Jan Kučera (a.k.a. LMN128) in 2020, based on a lot of experience from developments of the universal FPGA interface named MB03+. It is the first (and only, as of 2022) clone with 100% hardware and display timings aligned with a digital video and sound output (incl. HDMI). It uses the real (faster) Z80 CPU switchable from 3.5 MHz up to 20 MHz, which can be overclocked to 30 MHz – or changed for a T80 core at higher speed. Other logic circuitry is integrated in the Alchitry AU and AU+ FPGA modules, attachable to the eLeMeNt's motherboard. The eLeMeNt ZX combines 48K, 128K, +2, +2A, and many Russian memory models – including four Pentagon (computer) and several other Russian models – and the most popular interfaces, such as: K-Mouse; TurboSound FM; Sound Interface Device (SID); enhanced Covox and Soundrive; DivMMC; Z-Controller; Timex and advanced HiRes 512×92 with attributes and planar-based and chunky HGFX graphics modes; ULA+ and indexed true colour palettes; USB mouse and keyboard; 2 interchangeable SD card slots; 3 joystick slots, supporting 2-button Kempston and 8-button Sega controllers; USB serial connection with PC through a standard USB-A cable. The eLeMeNt features the original ZX bus (1x external, 2x internal), a USB-A serial connection and a rich internal pinout expansion for other modern peripherals. The eLeMeNt has 2 MB of RAM, which is upgradeable to 4 MB. The ROM system supports 16K to 64KB ROMs, plus SetUp (BIOS) ROM, Rescue ROM, and the latest version of the modern FAT and POSIX-API based filesystem: esxDOS. Humble 48 A spanish clone, introduced in 2017. Karabas 128, Pro The Karabas-128 is a ZX Spectrum 128k clone developed by Andy Karpov, based on CPLD Altera EPM7128STC100. The Karabas Pro is FPGA based clone with FDD and HDD controllers. N-Go A clone of the ZX Spectrum Next. SAM Coupé SAM Coupé was an
