One of the VIAs in the 1541 has a completely unused 8-bit data port.
(Some bits of it are used by the 1541C and maybe 1541-II for an optical
track 0 sensor.)  Anyway, check which of the VIAs has nothing connected to
pins 2-9 and connect a flat ribbon cable to those pins.  If I remember
correctly, pin 2 was bit 0 and pin 9 bit 7.  Connect the other end of the
cable to the C64's user port contacts PB0-PB7.  That's it.
