Fix Memory Issue on ZX Uno (crowdfunding version)

Post by TomD »

Does anybody on the forum have experience in fixing an old ZX Uno board. I've had it since the crowdfunding way back in 2016 but it has unfortunately developed a fault. I loaded the PCB Tester to the FPGA (with my Pi400) and it is showing FST/SLO RAM ERROR so going to guess the SRAM is bad?

Any help is appreciated.

I don't know if he does repairs, but this is his web page, maybe he can give you some info or advice, how you could solve that problem.
