I remember that one, it was used with some Norsk Data ND100 (16bit)
systems. I still have a power supply unit for the ND, it isn't
physically very large but the +5V can provide 200A.. (there used to be
a +5V 300A PSU in storage too but it went before i could grab it).
The ND-5000 (32-bit) systems used an FPS 5000 unit and I'm a bit more
familiar with that one.
