1)  Make sure you close the dip switch #7 on M2263SA.  It should be
    the switch for synchronous mode transfer.

2)  Remove the terminating resistors from the drive in the middle of
    the SCSI bus (in this case it's the M2263SA).  If you've tried this
    already, please ignore it.

3)  The parity checking doesn't seem to matter much.

4)  You can have any number of open connections in the middle of the bus.
