Description

ZX NUCLEON 512KB - Pentagon (ZX Spectrum) clone

New version with improved picture quality!

Finished and tested PCB + SCART cable

Tested with DivIDE 2k14 (Lotharek version), DivMMC Lite (Bytedelight version), CSSs Delta Disk

ATTENTION! All orders will be because of overcrowding production capacity settled in early 2020.

 

ZX NUCLEON 512KB is a new clone of ZX Spectrum computer, respectively Pentagon 128KB/512KB computer. The motherboard is the same size as the ZX Spectrum 48KB computer board and will fit into his enclosure.

Electrical wiring is largely based on Pentagon 128KB/512KB computer and keeps timing important parts of the computer! ZX NUCLEON 512KB uses modern SRAM memory instead of historical dynamic RAM. There are also some minor modifications, bug fixes, and a better video part including RGB video output. The computer also contains a program sound generator AY-3-8910A.

Important improvements opposite all competing projects: All I / O signals between the CPU and the bus are amplified by drivers!
This means greater capabilities and reliability with connected external peripherals and CPU protection against damage.

 

Why buy ZX NUCLEON 512KB and not another, competitive project?

The vast majority of the best quality software from the 199x-20xx period comes from the countries of the ex-USSR. This software largely uses Pentagon timing and does not work on ZX Spectrum and its derivatives. That's why ZX NUCLEON is the best choice for the future.

 

Changes for version 2A:

The new version includes two changes:

1) Changing the video part for improved image quality - modified wiring and component values. ATTENTION IMPORTANT! Composite AV video signal completely removed, a new better S-VHS signal instead. RGB of course preserved :-)

2) New PCB color red
