/* Clone of the F1-D controller */
=== Clone of the F1-D controller ===
A clone of the F1-D controller was created by [[Hans Hübner]] of [[FutureSoft]] in 2024. The card fits on the Mother X4 board and doesn't contain an extra ROM slot. Using [[FutureOS]] this card allows to add four additional floppy disc drives to the CPC, being called E, F, G and H.

=== FDC I/O Ports ===
On the F1-D Reproduction board the ports FA7E, FB7E/FB7F and FBF6/FBF7 are fully decoded. FB7E/FBF6 is chosen with a link/switch on the PCB.
On the F1-D original device the I/O ports are partially decoded(use of the full I/O address given below avoids conflict with other devices):
