The hard drive would require a controller, and a bunch of I/O pins. The current SD reader actually creates MFM to feed back into Paula which functions (among other things) as the FDC. Realistically, the amiga doesn't have an FDC ala NEC 765/Intel 8272. The amiga uses Paula as the DPLL, data and clock recovery, and provides indication of MFM SYNC. The CIA chips provide both input and output floppy control signals. The coordination of everything all together is handled by the CPU using trackdisk device within the ROM. MFM decoding is done via blitter within Agnus. There are add-on devices to add functionality, but they likely wouldn't be easy to interface...... Keith
