What is it?

Stand-alone FPGA Retro-Computer. Fits in the original ZX Spectrum 48K/48K+ cases. Features on-board keyboard membrane connectors, 2Mb SRAM (10 ns), 16MB Flash memory.

Why did you make it?

I have been an active contributor to the keyboard firmware for this product developed by ManuFerHi, the latest and final version of it can be found here

Being an open project, there are sources and gerbers for its construction. I wanted to build one and put on sale the rest of PCBs that I have assembled that I have left over, the one that I now offer is the last available, after the sale I will withdraw the item.

What makes it special?

The ZX-UNO its a complete stand-alone retrocomputer based on a FPGA. It can mimic the behavior of various 8 bit classic computers and game consoles.

The ZX-UNO (on which it is based) is designed to run mainly as Sinclair ZX Spectrum machines (48K/128K/+2a) with DivMMC support (MMC/SD/SDHC storage), ULA+ (multi-color, high resolution graphics), turbo sound (double AY chip), among other things. Nontheless It also can run as many other retrocomputers and consoles like the Sam Coupe, Jupiter ACE, Apple II, VIC 20, Sega Master System, NES, Atari2600, Atari 800XL, MSX1, C64 and a few more...

This product is build upon the amazing work done by the ZX-UNO TEAM. This version is designed to be fitted inside the original ZX Spectrum 48K/48K+ cases (or the available replicas by Retroradionics, like the one I offer as an option). Features membrane connectors on-board to let you use your ZX rubber keyboard.

DB9 joystick and SD connector (microSD is now available and it is solded) can also be sent stand-alone but if you solder them, you would have to cut holes on your case for access these. -> Indicate it as a comment when ordering

Attention! ZX Spectrum case/membrane/faceplate/rubber-pad are not included!

To this version I have not added the circuitry for the use of a speaker inside the case, but through the external jack or the SCART, the audio works perfectly
