CTM64 Button Board and Front Panel
As an addition to the CTM64 main board a button board with 64 momentary switches is
available. The switches are arranged as an 8 x 8 matrix. The connection between the CTM64
main board and the button board is established by four 16-pin ribbon cables. In addition the
common connector JP6 of the main board has to be wired to one of the corresponding pins of
the button board (only one of the three pins of the button board is used for this). Even any kind
of single-pole connector can be used for this connection to enable a separation of the two
boards without soldering.
