The founders of a crowd-funded project to make a retro computer games console, backed by Spectrum inventor Sir Clive Sinclair, have distanced themselves from the company they used to run.
Retro Computers has received £417,375 $542,000 from an Indiegogo campaign.
But former directors Paul Andrews and Chris Smith said they had been unable to answer backers' concerns and were now "publicly distancing" themselves.
The company accused Mr Andrews and Mr Smith of developing a rival product.
It has also attempted to crowd-fund a retro computer device - although its is based on the Commodore 64 - but failed to meet its target.
