The GEM Realpiano expander is for sale.

For some people it might be the module with the most realistic piano sound.

In good condition. It also has the last updated EPROM that GEM had released.

The problem with the screen playing them sometime (sometimes too soon) is well known for these modules (mentioned on wikipedia).

So I replaced it with a new one (black letters on a white background instead of green), of a different type, which will never show the problem.

Shipping with Boxnow and payment with paypal , only.

PS: Extra photos on request.
