''[note 8]'' The plug-in mode is supplied to the mainframe either as a resistor connected to ground (with 5% tolerance), or by supplying a DC voltage (with 0.25 V tolerance): | ''[note 8]'' Inter-Plugin Connections − In 1<sup>st</sup> generation 7000 series mainframes ([[7704]], [[7504]], [[7503]], [[7403N]]), pins 26B, 27A/B and 28A/B are inter-plugin connections. In the 3-bay mainframes, right vertical slot pins 27A, 27B, 28A, 28B are connected via 50 Ω striplines to horizontal slot pins 27B, 27A, 28B, 28A respectively, with ground on 26B. Four-slot mainframes additionally make the same connections from the left vertical slot to the right horizontal slot. ''More information needed - were any plug-ins made that used these?'' | ||
''[note 9]'' The plug-in mode is supplied to the mainframe either as a resistor connected to ground (with 5% tolerance), or by supplying a DC voltage (with 0.25 V tolerance): | |||
