1) Table 18.1 puts the IEC_O register at DC01. The source code and my debugger show it at D681, just above IEC_I. (DC01 is a VIA register)

2) Table 18.1 shows ATN_i as bit2, and ATN_o as bit4. The source code and my debugger indicate that both should be bit4

Should be corrected now. Please let me know if it looks right.
