According to the SCSI-2 draft revision 10L, atari_NCR5380.c is correct when it says that the phase lines are valid up until ACK is negated following the transmission of the last byte in MESSAGE IN phase. This is true for all information transfer phases, from target to initiator. Sample the phase bits in STATUS_REG so that NCR5380_transfer_pio() can return the correct result. The return value is presently unused (perhaps because of bugs like this) but this change at least fixes the caller's phase variable, which is passed by reference.
