=== FDC I/O Ports ===
All types of floppy disk controllers for the F1-S/F1-D/M1-S/M1-D range are based on the NEC 765 chip. The manual states that on "controllers having an integrated ROM module/eprommer" (probably the later 6128 interfaces?), the port addresses can be freely configured using a decoder ROM.
