Look at that rectified power supply. The transformer is enormous, guessing about 15 kg, and the filter caps could shock an elephant. The ripple noise would have irritated open collector logic.

I assume that's the reason for the 2 giant capacitors.

The whole unit weighs 40lbs (~18kg). The default power supply output 380 watts, and there was an optional larger one with 480.
