  1. I’ve got a C64 with the motherboard ASSY No> 250407 Artwork NO. 251137 Rev B. Did you want images of it? (its in fairly rough shape)

    1. Dear Johan,

      There are references to this mainboard, but sofar nobody has seen it.

      So if they exist in a very small quantity or they are never released.
