ZX NUCLEON 512KB - Best ZX Spectrum clone today

ATTENTION, this is a preliminary trailer for a new product that is being prepared for production.
It is not about selling the device itself!
By purchasing here you reserve the leading position in order for the product.


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.

Expected release date: September / October 2019.

Thank you for your support and have a nice day :-) CSS Electronics
