Like other 75xx and 76xx mainframes and the 7504, the 7503 has a linear power supply, as opposed to the switchmode supplies used in the later 4-slot mainframes. | Like other 75xx and 76xx mainframes and the 7504, the 7503 has a linear power supply, as opposed to the switchmode supplies used in the later 4-slot mainframes. In addition to the +5 V, ±15 V, ±50 V rails common to the 7000 series, internally (not on the plug-in slots) it has a +75 V output not found in later models, and a +150 V instead of the later +130 V. | ||
