Ah OK. I can see your trouble with ZX-UNO. Most of it seem to be Forums/Websites in spanish language. A real problem for those not speaking this language. I think best post it in "Hardware" here. But you too have the option to send PM to someone you read here who owns a ZX-Uno. No problem.akeley wrote: ↑Sun May 24, 2020 3:58 pm This is the only live Uno thread on this forum I could see, with possible high-concentration of Uno users (who are otherwise a reare breed), so I though a a few unrelated posts wouldn't really cause that big a disturbance. But okay, whatever.
I must admit though, that of all my retro-purchases this is the only one I truly regret - it's been nothing but headache since day one.
I think you´ve see this in englisch: http://uto.speccy.org/zxunofaq_en.html#unbrick but maybe require this: http://svn.zxuno.com/svn/zxuno/stable/binaries/BIOS/
Good luck with un-bricking!
