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 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 recently available replicas by Retroradionics). Features membrane connectors on-board to let you use your ZX rubber keyboard. Functions like NMI, RESET, screen mode switch, etc are accessible through keyboard shorcuts. We also offer an expansion board for external DB9 Joystick, VGA and PS2 keyboard connectors.
DB9 joystick and PS2 connectors can also be soldered on the main board but you would have to cut holes on your case for access these.
Attention! ZX Spectrum cases/membranes/faceplates/rubber-pads are not included!
