/* 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 ===
All types of floppy disk controllers for the F1-S/D and M1-S/D series are based on the NEC 765 chip. The manual states that 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 "controllers having an integrated ROM modulethe PCB. On the F1-D original device the I/eprommer" O ports are partially decoded (probably use of the later 6128 interfaces?full I/O address given below avoids conflict with other devices), the port addresses can be freely configured using a decoder ROM.:
'''CPC 464:'''
| 0xFA7E || motor on/off
|}
Legend:
x = not decoded. don't care, 0 or 1 can be used.
0 = must be 0
1 = must be 1
FDC:
I/O address A15-A0:
xxxx x0x1 0xxx xxxr
A10=0, A8=1 and A7=0
r = connected to A0 on NEC765 and selects status register or data register.
Motor:
I/O address A15-A0:
xxxx x0x0 0xxx xxxr
A10=0, A8=0 and A7=0
x = not decoded. don't care, 0 or 1 can be used.
only bit 0 of the data written to the port controls motor state.
'''CPC 664/6128:'''
| 0xFA7E || motor on/off
|}
On the board above marked 664 there is a patch wire which disconnects A7 and connects A3. This changes the decoding from FB7E/FB7F to FBF6/FBF7 for FDC.
FDC:
I/O address A15-A0:
xxxx x0x1 xxxx 0xxr
A10=0, A8=1 and A3=0
r = connected to A0 on NEC765 and selects status register or data register.
Motor:
I/O address A15-A0:
xxxx x0x0 0xxx xxxr
A10=0, A8=0 and A7=0
only bit 0 of the data written to the port controls motor state.
The I/O port decoding for the 6128 specific board is currently unknown.
