The national video game museum in Zoetermeer has an 48 Sinclair spectrum with a built in Casthe picture aboveduino but recently it became unreliable, it seems the 4116 RAM chips had became unreliable and even a small mecahnical bump on the tale could lead to a system crash. So we decoded to remove the RAM chips, and replace them with dual wipe sockets, and install new 4116 chips. I did the work and the result can be seen in the picture above. after inserting eight new 4116 the Spectrum worked flawless.
