Issue 5A, also known as the “KS3” as it was the third KickStarter campaign.

The Kickstarter campaign started in July 2025. The FPGA now is an Artix A7 XC7A35T-2CSG324C and memory has doubled to 4096 Kb, making it possible to run the Sinclair QL and Commodore 64 cores which are included, besides the ZX Spectrum Next core.

Production was delayed because of the unavailability of the ADV chip, used in the video circuit which will allow it to output more colours than previous models. Thanks to trade wars between the USA and China, the ADV chip was reclassified as ‘automotive’, meaning it could no longer be sourced in China. 

Production of the motherboards started in May of 2026 and in August the computers were shipped from China to Europe and sent to the backers in early November.
