* connect pin 1 (A8) of each new IC together. Either on the backside of the motherboard or directly at pin 1 of the ICs (*)
(*) according to the schematics pin 1 should be unconnected on the motherboard. As this was different on e.g. a 464 and there are different revisions of the 6128 board it's better to check this on your motherboard. In case pin 1 is connected to GND or VCC, you have to bend up pin 1 so it's not connected to the socket and then connect pin1 of all ICs directly. This is shown in the picture here [[File:CPC6320_A8bottomVsTop.jpg|thumb|none|A8 directly vs on motherboard backside]]
Now it's a good time to test if you have done everything right. Connect one of the A8 pins to GND with a wire and start the CPC. Run the diagnostics tool or a 128KB game. If you have done everything right, it should now behave exactly like a computer with 128KB built in.
