''[note 4]'' Not provided by most mainframes (digitizers only?). [[7A16P]] connects B27 to A9, requires −5.2 V on A27.
''[note 4]'' Not provided by most mainframes (digitizers only?). [[7A16P]] connects B27 to A9, requires −5.2 V on A27.
''[note 5]'' According to the [[Media:Tek 11000-series plug-in to main frame interface manual.pdf|11000-series interface manual]], ''many 7k plug-in units ground pin B21 or connect it to pin A21'', and ''The [[7D10]], [[7D11]], [[7D14]], [[7S14]], and possibly some others have pin A21 grounded''.
''[note 6]'' A22 = Busy output from [[7D12]], [[7D15]], B22 = /Hold input to 7D12, 7D15; no corresponding mainframe connections known
