Before you hack a peecee power supply, check the fan in the Amiga supply. If it's dead or just stalled, the supply will shut off. You can disconnect it and try it on another power supply or even a car battery.

@Odious

It looks to me like you have one of the original German Amiga 2000s. To quote from the Source. :-)

MotherBoard Revisions according to Dave Haynie:

A2000-A german, like an A1000 in a different box, 512k CHIP, non-standard processor and video slots

Yes. The orginal A2000 was designed in Germany. It was based on an integration of the A1000 motherboard design and the example Zorro II backplane from "Schematics and Expansion Specifications", the A1000 hardware manual. It used the thin Agnus, which handled only 512K of DRAM. They added a "Genlock" slot, which was essentially just the 23-bit video signals on an internal connector, and the "MMU" slot, which was essentially just the A1000 external edge connector on an internal slot. The machine shipped with 512K of Fast RAM in this slot, though the case was slow and had some reliability problems. About 60,000 of these machines were made, so I've heard.
