Hello everyone

The seller was super nice about the refund.

Not only he did a full refund and he asked me to keep the modules in case in the future I get access to a 6volt board.

I promised him to compensate for his kindness if I can get it to work.

I did remove the CPU and the eprom from the sockets and used contact cleaner spray plus air to dry. After carefully reinserting the
chips the same issue persists. Random lights flashing on the board and module. And garbage characters on display.

I am going to try to purchase a CPU from ebay and if possible a replacement programmed eprom from a member here if any one is able to sell me one.

I feel bad for the seller to be honest.

I will try to post pictures here.

Thanks for looking in to this for me all.

Murat
