There is a difference compared to a real drive: the disc motor signal is not connected internally to the Gotek. This means the ready signal will be active even if the disc motor is off.
EDIT: This is true for the old models. The new model SFRKC30.AT4.35 can pass the motor signal and reacts (delayed if wanted) to it for the ready signal. See below for Flashfloppy firmware.
==HxC Floppy Emulator firmware==
To best attach the Gotek to any CPC, use the following FF.cfg setting:
# Floppy-drive interface mode
interface = shugart
# Host platform
host = unspecified
# Pins 2 & 34 output (drive->host) manual configuration
pin02 = high
pin34 = rdy
# Rotational offset of disk after a track change
track-change = realtime
# Rotational offset of disk after draining a write to Flash
write-drain = realtime
# Index pulses suppressed when RDATA and WDATA inactive?
index-suppression = yes
# Milliseconds from head-step start to RDATA active.
head-settle-ms = 12
# Milliseconds delay from motor-on to drive ready.
motor-delay = 200
<pre>
# Floppy-drive interface mode
interface = shugart
# Host platform
host = unspecified
# Pins 2 & 34 output (drive->host) manual configuration
pin02 = high
pin34 = rdy
# Rotational offset of disk after a track change
track-change = realtime
# Rotational offset of disk after draining a write to Flash
write-drain = realtime
# Index pulses suppressed when RDATA and WDATA inactive?

# Milliseconds from head-step start to RDATA active.
head-settle-ms = 12
# Milliseconds delay from motor-on to drive ready.
motor-delay = 200

The rest of the settings can be used to your liking as they depend on preference and not on hardware emulation.

==Physical connection==
To connect the gotek to the CPC, you can directly connect it to the DDI-1 cable connector (you would need to cut off the noses on the bottom of the cable). It can work both as A drive (no 3" drive required) or as drive B. It can even work as a 3.5" or 5.25" drive for example with parados or VDOS. Please be aware that you cannot use an unmodified DDI-1 together with the Gotek without a normal 3" FD-1 drive. That is because the FD-1 delivers the 5V power to the DDI-1 and without it, it simply does not get any power to run.
You can also connect it to the original cable using an extension like this one:

There is no cablemode required - neither for the CPC464 nor for 664/6128 external disk connector.
