The GCTU1A is the main processor for the CTX28. It is shipped with the CTX28 Base cabinet.

To install the GCTU1A into the CTX28

2.Set the P601 battery jumper to ON (see Figure 1-10) and insert the GCTU1A (shipped with the cabinet) in the upper slot of the GMAS sub-motherboard (see Figure 1-6). Place it next to the guide rail of the PCB stopper (see Figure 1-8).

3.Secure the PCB stopper with the original two screws.

4.Insert the SmartMedia card (gold contacts face left, notched corner faces forward and up) into the SmartMedia slot on the GCTU1A (see Figure 1-6).
