Good morning,

I'm willing to buy a 16K RAM extension for my ZX81. If any of you has one to sell, please contact me.

Best regards. Bruno.

You can also build an external one on a stripboard: 16K RAM EXPANSION on strip board.

Edit: If the ZX81 is inside it's case, you would have to add space between the edge connector and the ICs. Otherwise the case will prevent it to be inserted in the port.
